I had a similar experience with an anti-biotic...it set off my worst symptoms again. I'm still trying to get it under control. I took budesonide for a long time, until the side effects became too bad, and when I went off it I found out how your symptoms come right back. I'm working with my GI doc to try some less invasive stuff, but if that doesn't work, I'll probably go to the Mayo Clinic when the weather gets better.
