Have had all the necessary tests including my last colonoscopy in July and sigmoidoscopy in November. However, for the last few months it started with incomplete evacuation and the last few day it is terrible pain when stool or gas pass around the decending loop and left side of my stomach. Going to the bathroom makes the pain stop but even gas can make it hurt until it passes. Just got off the phone with my GI specialist who said there is nothing there, take your bentyl and a hot bath because it is a spasm. Don't worry about it. Well I do and I am. Does anyone else experience this. When the evacuation is incomplete I have to take a warm enema and then it all comes out and I feel better. Thank you for your support.
