It sounds to me like you are allergic to the 5 asa's(asacol, lialda, pensasa etc.). I got really bad stomach pain, joint pain, rash, itcy etc. I can't tolerate any 5 asa's. I also can't tolerate imuran and I had one remi infusion and had some kind of reaction. I will try remi one more time. Good Luck! The onlything that has taken me out of a flare is pred. But it is making me crazy.
Best of Luck to you!
