Joint pain is one of my UC symptoms. And it's never the same area either (it's affected both shoulders, ribs, wrist, etc). My dr and I are currently trying to adjust my remicade schedule bacause I seem to have issues when I have a few weeks left to go before my next infusion. Joint pain is one of these issues. He has given me Darvocet in the past, and this last time since it was pretty severe, he gave me Tylenol 3. I'm hoping we'll change the remicade to be every 6 weeks to avoid these issues altogether, but yeah, in the meantime, I completely understand your pain.
