Rhinitis in the Colonoscopy Patient

Laying in the recovery area I sneezed, hard, five times. My right nostril burned. I pulled the oxygen off and asked my husband what the O2 measurement showed on the monitor above my head. “94% – it just dropped 3%”. I took deep breaths and the number popped back up. As my nurse walked into the room, I requested removing the oxygen measuring device from my finger. She said “Let me get one more set of vitals”. I sneezed a few more times, my nose running and burning.

Coming home that afternoon after my colonoscopy I continued to sneeze, the burning sensation in my right nostril got worse and the runny nose persisted. It was time to do what any competent physician (or e-patient would do) – I googled it. Apparently this is a common problem after colonoscopy these days.[1] It turns out that with the addition of using propofol for colonoscopies, anesthesiologists insist that a high flow rate of oxygen be used during the procedure to reduce hypoxia (a low oxygen level) and the use of capnography, or measurement of carbon dioxide retention. In order to do this, as best that I can ascertain, they pump oxygen in one nostril and measure CO2 in the other. That’s a lot of hi-flow oxygen going into one nostril through a nasal Screenshot 2015-04-08 20.02.44cannula. There are studies related to the irritation this causes in patients as well as a reduction in patient satisfaction. It’s day three after my colonoscopy and I am still sneezing, my nose still burns and I still have a fair amount of rhinitis. Yeah, I’d say that’s a dissatisfier.

Just a heads-up to my patients about to undergo your routine endoscopy. The misery may not end once your bowels are back to normal. Take plenty of kleenex.

  1. Very interesting. These were my exact same symptoms yesterday after colonoscopy under propofol sedation. All day long I was dripping and sneezing to the point of taking diphenhydramine to make it stop. And yes, only one nostril (right) stung, burned, and tickled–triggering continued dripping and sneezing. This morning I searched “rhinitis after colonoscopy” and Google auto-filled the search string before I could even finish typing it! Then I knew this was a common problem. My original concern was some type of community-acquired bacterial sinusitis. The hospital had been undergoing some remodeling yesterday and they had the AC turned to a higher temperature than is customary in that setting. So the procedure area and recovery rooms were pretty warm. Worried me that I might have caught a bug! Thank you for posting this thorough review of your own experience.

    • I am experiencing the same with my left nostril following a colonoscopy. I started to sneeze++ in the recovery room and my left nostril is running. My left eye (Day 2) has started to run as well but I am not sneezing as much today. It’s like I’ve got a bad cold and it feels like something is sore in my left nostril.

      • I just hand hand surgery for a cyst removal and woke up feeling great but then the sneezing started and by the time my husband got me to the car my eyes and nose were dripping and running like a faucet. This is day three for me and don’t feel much better. I haven’t had a cold in about seven years. All has to do with that blasted pronged oxygen tube they put in your nose I suppose and it has to do with the knock out drug and hose regardless of what type of surgery. Thank you for these posts as they don’t make me feel all alone in this.

    • Yes exactly the same … Due to excessive sneezing I have also just looked it up on Google to find out what on earth is going on …. Same procedure of a colonoscopy with a cannular for sedation and a tube in my nose for oxygen … At least I know now!

    • I had a colonoscopy under proprofol yesterday and immediately upon waking up in the recovery room I was sneezing. I asked the nurse why I was sneezing so much? She said it is probably the air conditioning. Today – the 2nd day after I am still sneezing, my left eye watering like crazy and my left nostril running. I googled the symptoms after colonoscopy and found this is a common thing after colonoscopy after mod to deep sedation. I also called my Dr’s office and was told it is from the oxygen and tubing.

    • I just had a colonoscopy this morning and have been sneezing ever since. Thought I was crazy! Glad I googled it and found that others have experienced this as well. I will definitely let the doctor know when his office does their follow up call tomorrow.

      • I need relief! Thanks for this article. I just had a colonoscoy and my right nostril is burning and running. I thought I was having some kind of alergy attack. But than I remembeted I take Claritin everyday and did so after the procedure so I should not have a problem. Than I googled and here it is. Is there a way to get relief? They need to tell the nurses to grease our nostrils before the 02 is put on. I think that might help. Ineed relief.

        • I had my procedure Monday at 8am……it is Thursday morning and my nose is still running like a faucet, sneezing, coughing (post nasal drip) I feel like I have a bad cold. I stayed home from work yesterday because I work with seniors and I feel bad going to work and coughing all day. I have read this lasts about 4 days, hoping today it will stop……and I thought the PREP for colonoscopy was bad……this is ridiculous!

  2. Today was my third colonoscopy. Shortly after I awoke with a “stuffy” nose, I began sneezing with a “hay fever” like reaction. After I got home it has continued unabated and is very annoying. I wondered if it was possible to wake up with a “cold” but it made more sense to me that it was an allergic reaction. So I googled it. Wow. I do not have many allergies except dust, and some pet dander so I rarely get these symptoms without a cold. And of course none of this was in the short procedure unit. This article makes the most sense, given I did not go through any of this in my last procedures. I feel pretty certain it was from the nasal O2. I appreciate this information.

    • It’s the O2 but it is due to the anesthesia department using a CO2 monitor in one nostril and high flow oxygen in the other. This needs to change but won’t until patients start complaining.

      • Thanks for your input. Same thing here after a colonoscopy today. I am a RN and I figured it was the O2 and long nasal prongs but seeing your post confirmed it. They really do need to rethink this. Going in for a colonoscopy and coming out with full blown rhinitis was not part of the plan LOL.

  3. I expperenced the same , I mention my sore nose a number of times to the nurses and commented that I felt like I was coming down with a cold. I felt shocked It had come on so sudenly , do the nurses/ doctors know the procedure can cause this ?? I would have greatly appreciated a warning . I will defenatly need extra time off work if I get it done again

  4. Same thing! I had it done today and I really want it to stop. Just when you think it is over, this misery starts!

  5. This happened to me as well. It’s been three days and my left nostril is still irritated and drippy, and I keep sneezing. Why do the doctors do this to us????

  6. Just went through the colonoscopy today and experiencing the same problem. Is there anything I can take over the counter to make it stop.?

  7. I just had a colonoscopy and have been blowing my nose since I woke up. I was not sick at all before the procedure and do not have any allergies. I recently (within the month) had shoulder manipulation under general anesthesia and did not have this same reaction. I also googled it and found I was not alone. I would love to know if I could avoid this the next time. I also work as a nurse in a same day unit and take care of patients who are having EGD’s and colonoscopies. I have never heard this complaint but will be more aware of it if anyone comes out with a runny nose.

  8. I can’t tell you how relieved I am to read your post. Had my first colonoscopy this morning so I had no point of reference to compare my symptoms to. I too thought it was a strong allergic reaction or coincidentally a cold was starting. My right nostril is like a faucet. I will be addressing this with my gastro doctor at my follow up visit.

  9. Day 7 after endoscopy sneezing has stopped but still feel the itch and burning in right nostril, eye is running and now have sinus pain. No fun….

  10. I just had a colonoscopy/endoscopy yesterday. I, too, have been sneezing like crazy. My right nostril is itching and dripping. I had never had this happen before with these procedures and had never heard it was a possibility. I just knew I didn’t have a cold. What actually causes this ? Is it a side effect of the sedation or from the nasal cannula ?

    • No–it’s a change in how anesthesiologist is monitoring patients. In the last couple of years more anesthisiologists are using a high flow oxygen in one nostril and a co2 monitor in the other. The consequence is discomfort in the high flow nostril and I suspect the placement of the cannula has something to do with it. Patients need to start complaining or it is not going to change.

      • Thanks. There are probably many people that have this happen and just assume they are getting a cold or allergic rhinitis. I was just glad to find out I wasn’t completely crazy.

      • I’m on day 5 and I feel horrible. I can’t even inhale thru my right nostril from the burning. I’ve tried benadryl and saline and Flonase. Nothing helps. Any idea how much longer this could go on? This is really so much worse than a cold!

  11. Are nurses prohibited from stating this after-effect? It seems the nurse spoke to me about everything but this. Right after the procedure (yesterday), the nurse came in and gave me a tissue box right away. But I was not informed about this until just now reading all the blogs.

    • No, I think it’s just a new problem and its from anesthesia not the procedure. Please complain to the hospital. Until people start complaining this will not change.

  12. I had rotator cuff surgery in April and started sneezing as soon as I woke up. The inside of my nose was very sore. It is now September and while my nose is better, it is not all better. Some days I don’t notice it and other days it’s uncomfortable. I am going to see an ENT Dr because I have another surgery coming up next month. Something different needs to be done.

  13. I also developed a fever which made be nervous along with the runny nose and sneezing. The fever is gone but cold symptoms are still hanging on. Did anyone else develop a low grade fever?

  14. Same thing here; I am in misery. The weird thing is that I can sleep perfectly fine, but as soon as I wake up the itching, sneezing and dripping begins. Does anything help this? Benadryl, Allegra, etc.?

    • oh me too! When I first woke up this morning I thought I was better (2 days following my procedure) but once I got out of bed, realized I was not. Its annoying!

  15. Kathy, based on your advice, I called the surgical center where my colonoscopy was performed, the doctor who did the procedure, and the anesthesiologist: No one wants to hear about this. I have been repeatedly told that I just have a cold or allergies. I know my body well enough to know what a cold feels like, and I don’t suffer from allergies. I keep telling them that I woke up from the procedure sneezing and with a runny nose and that those symptoms have continued for five days now. It has all fallen on deaf ears. The entire problem with the medical community in a nutshell – talking AT patients instead of WITH them. So frustrated…and sneezy.

    • I’m at a little bit of a loss as to how to bring this out. I think anesthesiologists just think this is “no big deal” and don’t want to admit to it being a problem. Also, I suspect it has some what to do with how the flow is positioned because not every one complains. But this has certainly hit a nerve in the patient population. It needs to be studied and fixed.

      • Well, I am feeling much better, but it was five days of misery. If they had let me know that this could be an issue or possible side effect, it would have been fine. It’s the lack of information that is infuriating. If it weren’t for this site, I would have thought I was going crazy. Thank you.

    • I am on day two now after having a colonoscopy with the oxygen in my nose mediately after waking up I started sneezing and sneezing and sneezing and sneezing my nose will not quit dripping this is ridiculous nobody told me about this I’ve tried Benadryl I’ve tried Allegra nothing is helping me this is Very disabling can someone tell me what to take to get some relief? The colonoscopy wasn’t bad it’s afterwords not been able to breathe or talk or walk and missing work terrible.
      I know I had a colonoscopy yesterday and I can’t quit sneezing and my nose won’t quit running I am so frustrated I don’t know what to do I’m going to have to call in work I’m so irritable and upset nobody told me about this side effect I would just rather have the old colonoscopy like they did before I had no side effects with it

  16. I am a physician and had never experience any symptoms after multiple colonoscopies and upper endoscopies. I had both procedures today and after 8 hours , I’m still miserable from the headache, sneezing , nasal congestion, sinus pain, severe ocular pain with excessive tearing. It’s a relief to know these are not uncommon. I’ll make sure I tell my gastroenterologist I would want a different type of sedation next time.

    • I had a colonoscopy yesterday and I’m miserable I can’t quit sneezing and my nose won’t quit running this is so agervating and miserable I am so upset no one told me about the side effects I had a colonoscopy before and this never happened what did you do to quit sneezing and nose quit dripping I’ve taken Benadryl and Allegra and nothing seems to help.

  17. I had a colonoscopy yesterday – Immediately after waking up in recovery I was sneezing. I asked the nurse why I was sneezing so much and she said “it is probably the air conditioning”. By the time I got home my left nostril was running like crazy and the sneezing continued. The next day (today) My left eye has been watering all day in addition to the sneezing and left nostril running. I googled first and found this forum and than called my dr’s office – at which time the nurse told me it is from the oxygen and tubing and will go away in a day or so. I was not sick at all nor have I had allergies ever prior to going in for the colonoscopy and having gone to sleep for this procedure.

    • It’s not from the oxygen or the tubing directly, it is from the set up of high flow oxygen directed into ONE nostril. This is absolutely not necessary but have no idea if anyone is working on a better way to accomplish the aim of safely keeping patients oxygenating while not making them uncomfortable for days after the procedure.

  18. Thank you for your post! I had my colonoscopy on Friday, and I had a runny nose (right nostril only) and was sneezing constantly the minute I got home and all day Saturday. The sneezing finally stopped today (Monday). I still have a runny nose, but it’s significantly better. Your post and all the comments from others helped me figure out my problem. I emailed my dr.’s office about my symptoms.

  19. I have the same symptoms! After waking up from my colonoscopy today I started sneezing and my nose has not stop running. I am still feeling the same symptoms . I will be putting this down on my patient survey and turning it into my doctor I will also let her know how miserable it is. I just took a Claritin and I’m hoping that will make a difference .

  20. I had my colonoscopy Wednesday my nose was burning after my procedure and then the sneezing started then the watery eye and nose like a faucet only my right side. Today is Friday and still the same minus the sneezing as much. I have this procedure every 3 years and have never had symptoms like this before. Miserable indeed… I knew it had to be from the oxygen but very glad I found this post, As for medication to relieve this nothing has helped me to dry up. I know the feeling when people are saying miserable.. I think it’s down right annoying, I am pretty sure the nurse knew what was up with me and just handed me Kleenex.

  21. I’ve got the same thing and called the place where I had the procedure. The nurse said she’s never heard this. Maybe if more people speak up about it, someone will finally look into it. It’s painful, tickley, and liquid is just pouring out my nose. I can’t blow it fast enough.

    I’m considering flushing my nose netty pot style with salt water. I haven’t taken any allergy meds yet.

  22. Thank you for the information. I just had a colonoscopy today and it started with my left nostril tickling and then it started running. Glad I know why now. I popped a Vitamin C worried I picked something up.

  23. I just had an endoscopy today at 1pm and have runny nose, eye tearing, and frequent sneezing. This all started on the drive home. When will it end? Is it safe to take a Benadryl along with my nightly 2mg Ativan for sleep tonight? Is this too much sedation after the anesthesia today?

  24. I had a colonoscopy yesterday and am too sneezing and only my right nostril is tickling and burning however I was given what can only be described as a sponge which was popped into my right nostril only, supplying oxygen, never heard of it being done that way but am still getting the symptoms as everyone else has described! Oh well at least I know it will pass and it isn’t painful just annoying!

  25. Had a colonoscopy about a year ago and propofol was used. Almost as soon as I awoke I had a massive runny nose…but just from my R nostril. Used about 10 Kleenexes right out the gate. Mine did not persist very long.

    Interesting to learn that the problem is due to the one nostril O2.

  26. Had a colonoscopy yesterday 12/7/16. Immediately, when the oxygen tube was put in my nostrils the right side starting burning terribly. Asked what was it, and was told it was oxygen. Said I’d had oxygen before and it never caused my nose to burn, thought I was having an allergic reaction. Was told it could be the plastic. I keep pulling the tube out saying something must be wrong, but they kept putting it back saying it would stop. He gave me the IV and next thing I was waking up and my nose was very painful. I took the tube out and asked nurse for tissue and starting blowing, thought I had something in my nose but only a little liquid came out. Then I started sneezing. I thought I had had an allergic reaction to something. No one said anything about this reaction being a common one because of the medication. Was a little afraid because I have asthma and a lot of sneezing can trigger shortness of breath. Thank God, didn’t have an asthma attack but have been suffering all day today trying to figure what to take to relieve symptoms. So glad this website is here so I have some idea what’s going on. Will definitely contact the doctor to let them know that patient should be advised of the side effects of this new procedure. Have had two prior colonoscopies without any kind of side effects.

    Thanks everyone for your input.

  27. I had a colonoscopy this morning and is soon as I woke up in recovery I started sneezing and sneezing and sneezing my nose is running and it’s been eight hours, this is miserable someone needs to report this issue. I called my doctor and asked the nurse she said take Benadryl and is not helping me at all. My nose is dripping like a faucet and I continue to sneeze. This is so frustrating!!!! I had a cold a couple weeks ago and just got over that about four days ago. This is ridiculous I’m so upset.

  28. Same thing for me today. I almost never sneeze, & this is ridiculous. So far I’ve only found one study that only deals with the type of delivery system:

    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3043006/

    Hope the link works.

    I tried a Vick’s nasal inhaler, knowing that Camphor & Menthol are mild anesthetics, but it only helped briefly. Next, I sprayed a 2% Lidocaine solution (marketed for burns) onto a Q-tip & inserted it waaay up into my right nostril. This worked a little better than the Vick’s, but it wasn’t a magic bullet. If I come up with any other ideas, I’ll post them.

    Good luck to all
    Janet K, Rph

  29. Thank you for your post. I am suffering the same misery and your information was very helpful. I have had 2 surgeries, spinal and foot surgery in the last few years. A colonoscopy and this was my 3rd Endoscopy and never had this occur. This is day three after procedure. When the nurse called day after, I told her no after effect from Endoscopy but told her about severe nose drip, irritation of right nostril and constant severe sneezing. She told me probably from Anesthesia but could not give me an explanation. I will notify my doctor directly to make him aware. Strange also that as I noted in other postings that I slept through the night but as soon as I woke started sneezing again. Thank you again.

  30. I’m suffering from this. It’s horrible. You’d think that they would let you know it’s a potential side effect.
    I can’t breathe at all from my right nostril it’s that painful.

  31. Had a colonoscopy four days ago. The second one. I had forgotten how sick I got after the first one, until they took the oxygen off. I have been miserably ill with a head cold. Missing the rest of the week of work and most likely trudging through next week sick. I have asthma; I’m terrified this will get into my lungs before it’s done.

  32. Thank you all for posting. I had a colonoscopy yesterday and got severe rhinitis on the way home. Fell asleep after a meal and had severe sneezing on waking, right eye streaming. Woke up in the night with it as well. Right nostril burning. Washed nostrils with cold water, applied vicks liberally and turned the electric blanket on. Symptoms eased enough to go nacl to sleep. So relieved to discover it’s linked to the oxygen and not allergies.

  33. Just had my colonoscopy/endoscopy yesterday. Seems like a little thing to complain about but I have taken several OTC’s and nothing is working to relieve the symptoms. My nose is raw from blowing and and my eyes watery. What a mess LOL

  34. Well I guess I’ve joined the itchy, sneezy, drippy club. I had an endoscopy today and just like the rest of you, as soon as I woke up in recovery the itching n burning started in my right nostril. They had to give me benadryl but no one bothered to tell me what was going on. Funny thing is, I’ve had many surgeries and procedures under sedation, but this was the first time this happened. Hope it’s the last time

  35. I had a colonoscopy last Wednesday. Today is Sunday (day 5) and I am still not completely over the misery. I also woke up from the procedure sniffling and sneezing, and the rest of that day my nose was just like a faucet running with constant stabbing, tickling sensations. I began to rinse both nostrils with just plain water, and the stinging pain was horrible, but that seemed to help, so I have been continuing that up until now. The second day I called the nurse at the surgery center and she suggested Benadryl. I took two and it was no help. (The doctor who did the procedure never returned my call.) Yesterday the running nose began to slow down, but my eyes are still swollen and watery, and I have almost no sense of smell. I also am able to sleep, thank goodness, but when I begin to move around, the symptoms begin.

  36. Thank goodness for this post and all you beautiful people. Had my first colonoscopy/endoscopy today. When they put the oxygen on my nose, I immediately commented that it felt like a lot… no comment. Then I noticed that it felt like one side was not in my nose. This explains it perfectly!!! No relief with Claritan, tried some Vaseline up the one nostril that’s bugging me (helped a short while), and then Neti Pot… nothing. Guess I’ll wait it out. Thank you for the perfect explanation. I’m going to suggest they add it to the take home information. Geez.

  37. Thank you for posting this information. While I’m sorry to see so many patients suffering from it, it’s good to know it’s common. I had an endoscopy and colonoscopy this morning and have been bothered with sneezing and a runny nose since then. The left side is a bit congested my right nostril is running, itching and burning like crazy. I took cold medicine and it has not helped. They do need to tell you this is a common side-effect.

  38. I had my first ever colonoscopy yesterday. I noticed when the nasal cannula was inserted it felt uncomfortable. I tried to adjust it a little, but, still somewhat uncomfortable. Afterwards, in recovery, I awoke to sneezing & burning in only in right nostril. I kept sneezing over & over. My nose was running like a faucet. The nurse brouget me a box of kleenex, which I used most of by the time I got home. At first I thought my allergies were really bad, but, I decided something wasn’t right & Googled the symptoms. Sure enough, I found this forum & discovered I’m not alone in my misery. This is terrible. I cannot even function like this. I too, have noticed it doesn’t effect me while I’m sleeping, but, as soon as I get up…burning, runny nose & watery, teary eye…only the right side. I had awful headache yesterday, but, not today. I do feel slightly feverish, though.
    Nobody told me this reaction could happen. It’s now, Friday night…I hope it gets better very soon. I will be calling the facility where the colonoscopy was done & report my symptoms. I will also be calling my doctor. They really need to use another method of sedation…this is not right at all! Thank you all for sharing your experiences.

  39. had my colonoscopy on april 4th, 2017 and showed the same symptoms as above. sneezing and nose running like a turned on faucet. i tried everything i could think of, nose sprays ( three different kinds), double zyrtec, cold medicine, saline solutions in the effected nostril (only) left one, I suffered through the second day, my left eye dripping and getting more and more swollen when my husband said try ibuprofen and tylenol. so i took one tylenol and one ibuprofen and -bingo- after a short time the itching in my left nostril stopped and , therefore, the sneezing! just thought i pass this on

  40. I had my colonoscopy this morning. Same itching, burning, tingling, sneezing with massive unrelenting drainage focused mainly on the right nostril. I’ve nearly gone through a box of tissue so far. I used Claritin, Sudafed and nasal spray before googling and finding out my efforts will be to no avail. Everything about my procedure was textbook until this. I will report it on the questionnaire and to the nurse who calls tomorrow. It’s pretty horrible. If anyone has found anything that works to alleviate the symptoms or speed up the recovery, please share.

    • I just had my first colonoscopy yesterday with similar experience. I told my husband I was sure it was the oxygen. Thanks to all of you for sharing your thoughts. I am so miserable. I am done with colonoscopy. I pray I never have the need for it again. I wish they had warned me.

  41. I’m so glad that I was curious enough to Google my runny nose as an after effect of anesthesia. Years ago, my mother mentioned that there were instances where she had been administered an anesthetic for surgery, and had experienced a runny nose or cold post surgery and wearing off of the anesthetic. I had therefore heard about a runny nose as a side effect of anesthesia but had never experienced it. I had my third colonoscopy yesterday….when I got home and proceeded to rest, my left nostril felt dry so I massaged it a little and then applied some saline solution. About thirty minutes later, my left nostril started to tingle/burn slightly and then I began sneezing. I am still sneezing today….also with a runny nose/nostril and having to blow my nose intermittently. I guess I’ll have to suffer through it or use some Benadryl or Ibuprofen even though the doctor recommended no aspirin, etc for the next 7 days.

  42. Exact same symptoms as listed above after my endoscopy. Now if someone can create a list of things to try to manage the symptoms I would be most grateful.

  43. Wow! I thought the pre-op procedure for a colonoscopy was , but the immediate sneezing and MAJOR runny nose AFTER the colonoscopy is even worse! With the multitude of complaints just in this thread why don’t anesthesiologists find an alternative procedure than the heavy oxygen flow through the nostril. And most say it will last 3 to 4 days? I certainly didn’t have this problem 4 years ago with the same gastroenterologist. Come on doctors – remember “Do no harm”?

  44. Like everyone else I googled side effects from colonoscopy anastesia as I woke up with a snuffed up nose and within a few minutes started sneezing and I mean hard sneezing. I have had a tissue to my nose ever since and it is sometimes driving to the floor before I can grab a new tissue fast enough! I have not had a cold in about 8 years and figured initially it was allergies or as thesaurus went on that I picked up a bug at the hospital. But it did not feel like a cold really although it is making me feel miserable and my nose is raw after an afternoon and evening. While I read about possible side effects from anastetic and understand why they feel the need to do this, it would have been good to know and I will inform my doctor at my follow up appointment about it. Thank you to the persons above who got me informed. Positive is it is not a cold.

  45. Me too!!! I just had vascular surgery and immediately after started sneezing and my left nostril running! I’m on day three and beginning to lighten up. Although this morning I woke with hives left side abdomen. I am thinking this may be due to the nasal spray I was using to help with the runny nose! Bright side: Hives and runny nose are lessening the irritation of incisions!

  46. I am so glad I found this thread. I had colonoscopy yesterday 8:00 a.m.. started sneezing in recovery and still miserable 24 hours later. I have taken an antihistamine, used my daily Flonase. Nothing helps. I got no sleep last night added to the no sleep the night before due to the wonderful miralax.
    This is miserable and glad to see I’m not the only one. I guess you just have to live through it. Fortunately I am retired and don’t have a job to report to.
    I will definitely add comment to any survey I get and will ask about this if any other procedures come up.

  47. Had the endoscopy and colonoscopy this morning. Immediately upon “waking up,” right nostril was crazy itchy and I’ve been a waterfall ever since. Benadryl allowed me to sleep, but as soon as I woke and sat up, the buckets began again and I can’t believe this much fluid is in my body to begin with. I have to work tomorrow and am thinking of wearing a bandana across nose, robber-like, so no one has to see the involuntary nasal drip. And keep the tissues packed like a baby’s bib? There MUST be a better way. For all of it – including the Prep “beverage.” Nowhere near as painful as the diverticulitis, but almost as debilitating. I’m grateful to find this thread so I know I’m not alone.

  48. Thanks for posting. Had my first colonoscopy today. Procedure went smoothly. The aftermath not so. Dripping and sneezing is profuse. This may have a negative impact on my career. This can’t be acceptable medicine.

  49. I had colonoscopy surgery yesterday, and I too am suffering terribly from these same symptoms. I woke up early morning with what felt like a severe sinus infection and headache. A hammer to my big toe I imagined would be far less than the pain I felt in my head. Now, I’m not a doctor, but I am a pilot, so here is my uneducated but educated explaination and solution to your pain. Michael Jackson died from the use of propofol as a sleep aid. I suspect that propofol works as a anesthetic because it takes over your body and slows down its ability to maintain itself (respiration and heart rate). That is why we fall into such deep unconsciousness. Now, to counter this anesthesiologists pump in, through one nostril, near pure O2 (oxygen) in order to keep our cells and body alive. This insures that we do not lead to hypoxic asphyxiation, which leads to death. Now, pilots have to be mindful of this condition also. Because at altitude there may not be enough pressure to pump oxygen, or atmosphere into our bodies. And I say “atmosphere,” because we animals on earth’s surface do not breathe an atmosphere of pure oxygen. Without looking it up, I believe our atmosphere which we humans have adapted to live in only contains about 33% or less O2. Sometimes, other than when in emergency situations pilot will use our oxygen mask at a setting of 100% O2 to clear our heads and spike our awareness and mental processes. And then we come home to what we believe is Sinusitus caused by bacteria in the oxygen mask. So, in a sense, we are on an “oxygen high” or oxygen intoxication. I remember how good I felt after coming out of surgery. I had such good feelings and happy thoughts. I almost bought I and my wife brand new Ducati motorcycles as I visited the store coming home from surgery. Then the sinus trouble and headache, and sneezing the sentivity to light started. Intensified by the dry bright Las Vegas climate I live in. In otherwords I was suffering just like Migraine headache sufferers. Your cells are over-stimulated and now your sinus and head hurt. I also suffer over stimulation and pain from smelling perfumes and deodorants. So, the next morning, after a sleepless night, (I also had to call in sick from my next airline trip this morning) I.on an educated guess, took some Migraine formula aspirin and so far it has relieved the pain and sneezing. I hope this helps you.

  50. Oh, and also, your bodies, noses and heads are working feverishly hard to re-adjust to the non 100% pure oxygen environment we live in.
