Hi bigtruck, all of my large intestine was inflamed and had ulcers. My meds were pred, pentasa, one infliximab I cant remember any other. I was on treatment for nearly a month and none of it was working for me. Mine was extreme it all happened so quickly I had only been having symptoms for 4 months before I done anything about it. I think the Imodium that I got from my doctor a week earlier didn't help. My stomach swelled up like I was 9 months pregnant! I had an obsruction has well as still going 20-30 times a day unbeknown to me my bowel nearly perforated and could of killed me. I had to have an emergency total colectomy with ileostomy. Sorry I know this doesn't really help you but I hope you get well soon and they sort you out. Keep me posted you are in my thoughts xx
