I was on remicade and it caused remicade induce RA. But I have now stop it and went back on Imuran and now doing humira, all the joint pains were gone in a week. It was unbelieveable. I was seriously crippled and now I walk like I never had RA but I can say that my knees are still a bit deformed from the RA but no more pain.
But my doctor always said it was the crohn's that was causing the RA (I knew different) I don't suggest taking RA meds tho, sent my crohn's into a flar and ended up in the ER. What meds are you currently on?!
