Not sure if you are still around.... but I have to comment just in case. What happened to you while on Remicade happened to me. Exactly. It was my second time on it, and my second infusion. My lips, hand, heart... everything was crazy. My doctor told my I can no longer be on Remi, as I had built up antibodies. I had been pre-medicated with benadryl even.
I am not on Humira, since August, and just started a flare. :( So sad. Not sure what I can do next... I am alergic to all 'Pentasa' like drugs.
I am wondering... have you kept your colon?
Sorry for your pain. If it helps any, I totally know it.
