I think my Gi doc is the same as your old doc. I went in last friday, and told her about the research I've done . How remicade might have caused antibodies, which may be causing the arthritis. She just agrred, no test nothing. So I really don't know if it's actually the antibodies, someone else said it could even be remi induced lupus. I'm thinking i need a new GI. But they are so hard to come by here in Montreal,Ca. The doc took me off remicade, put me back on Imuran and now waiting to start Humira. Hope these 2 meds will help my arthritis. Now my CD is out of control from not having remicade. I rather flar up of crohn's then these arthritis pains that are like no other.
