Hi, I had a colonoscopy yesterday morning. It went well, but soon after the procedure, I started sneezing a lot and by evening, my left nostril and left eye began running continuously. I was lying on my left side during the procedure. There is pain in my left nostril and I am feeling pretty miserable. I understand this may be a reaction to the drug, the plastic tubing for the oxygen or damage caused to my nasal cavity from the tube and/ or dryness cause by the oxygen. I have tried steaming and have managed to sleep a little. It is 24 hours later and I am still sneezing and my eye and left nostril are still running a lot. I have a headache and feel quite unwell. Is there anything I can do to feel better? Thank you! S
