I had a Colonoscopy in the 90s and felt everything it was very painful.  The Nurse;s told me that I had so many abdominal surgeries that is why.  My colon was like cement.  Can I be assured that I will not feel anything if I have another one I am now 55 and have not had one since because I am scared.
Hi and welcome to Chat Doctor. Thanks for the query. Well it is more painful if you had colorectal surgeries in past but so many years after surgery there shouldn't be some significant pain. Also, it can be dined under general anesthesia so consult your doctor about it. Wish you good health. Regards
