Immediately after completing a routine colonoscopy my right nostril began itching intensely and I sneezed constantly. No other symptoms whatsoever. This continued for three days and abated a bit when I used Boroleum ointment for dry nose, however I find that inside my nostril is now swollen and red and I am getting small itchy red bumps on the edge of that nostril. Could this be related to anesthesia? That nostril did run quite a bit off and on but now only feels itchy and stuffy with the swollen area. I have never had allergies and my other nostril has not been affected. I have tried applying neosporin and also OC cortisone cream to no avail. I work for eye surgeons and I am quite medically knowledgable but this has me stumped. Do I go to a ear, nose, throat doc or my gp? It has been a week and I am quite at my wits end. Thank you for your time. lananana
