I had a mild chemical colitis about 6 months ago diagnosed from a colonoscopy, from the time I got it I was always in pain and had reasonably loose stools. The pain was not going away so after 3 weeks I had another colonoscopy and the colitis had cleared completely up and my doctor said that the pain is probably due to my bowels being sensitive. It has been six months and I still have not had much improvement on my condition, but after taking some herb supplyments for bowel complaints I have had some relief. Everyone of my symptoms points to IBS.My question is ,has anyone else had IBS come on them suddenly? Or Did I already have the condition ,but the colitis made it worse? I have been concerned about ulcerative colitis too, as reading on the internet , chemical colitis can be a trigger for UC, anyone have any good info on that?
