Hi from another new member! I was really glad to find this forum, too...it is always comforting to know that you are not alone.
I have had UC for over 11 years now, and for the past 5 or so I have been successful controlling my flares with hydrocortisone enemas and Colazal. I have UC throughout my colon, but most of my recent flares have been isolated to the end of my colon - where the enemas can reach. As I understand it, if your flare is too far up into your colon, the enemas will not be able to get up far enough to work. Do you know where your inflammation is worst?
Unfortunately, I am now in the middle of a major flare that is not responding to enemas, so I am back on Pred and they are looking at Remicade as another option. Still, I did have great success with the other treatments for several years -- and an enema beats an oral steroid any day in my book.
I agree with the others, however, you need to find a doctor who will work to get you better and not just pass you off.
As far as exercise, I am in too much pain and too tired when I am flaring badly. When it goes down and during remission, however, I am really active - cardio, abs, weights, you name it. I think it does a lot to keep me healthy and a little less stressed. I am about to try accupuncture and think yoga could be perfect for the stress, as well.
