So sorry for your continued struggles
I agree completely with the previous responses. I always have asked myself if the symptoms I'm having now were around before UC. Certainly things can develop, but for me anyway, most of the symptoms I have with UC are related in some way. It is hard to tell, and sometimes you just have to address those symptoms regardless of the origin.
I am curious as to your diet. Could you share a bit what it's like. There are quite a few folks like Imagardner2 found great relief through diet after many years of marginal medications.
And yes, hang in there. We'll help any way we can.
