I started off with pain in my left side...within. Just a few days it has become so severe it travels down my hip and back. It has me walking all hunched over. That's the only way I can walk right now is bent over. Drs aren't sure what's going on. I've been told its my siatica then was told I have diverticulitis... Two totally different things. One has to do with a nerve...the other your colon. So.ebody please help me. I can't handle this pai much longer. I've been on a heating pad laid down for 2 days because I can't move.
