I always feel like I need to have a bowel movement and when I do it burns and I feel like I am being ripped apart and I scream because it hurts real bad. I am not constipated either. I always feel like something is throbbing or chewing at it. I can hardly sit it hurts so bad. I jwent in for a routine colonoscopy and a my Dr was to do it but a resident Dr jumped the gun and he went in and perforated my colon. I was in the hospital for 13 days and almost died and the Colon was still leaking after it was later that night sewn up.
