My "Crohn's related arthritis" has been flaring since January, even though my Crohn's is supposedly in remission. Humira is not helping with the joint pain, Ultracets aren't doing enough, and we've ruled out just about every other option. My stomach doesn't like the NSAIDS, my liver doesn't like anything else, including the methotrexate injections, which WERE helping but I had to stop (am trying them again now at a reduced dosage but they are not working at this dosage).
Volataren gel seems to help with specific joints, but I can't put it all over my whole body, so it's not helping much right now. But, that is something for some of you to try. It normally helps me and it doesn't have side effects like the pills do.
Definitely see a rheumy. My GI won't touch the arthritis, so I have to see her for that. They normally work pretty well together, but she recently wanted to take me off of Humira and put me on Enbrel, but my GI said no, since that won't help the Crohn's any. So, it has been very tough trying to treat the arthritis without aggravating the Crohn's.
