yes having IBS at the same time does make it hard to figure out which one is causing the problems. what does your doctor giving or doing for you? i was put on Remicade IVs. for Crohns disease. right now i'm in remission for that. you do know that Crohns, IBS, IBD, Colitis & Ulcerative Colitis are ALL in the same disease family? which affects the small intestine down to the lower colon with the rectum. have you had a recent colonoscopy?
