I have arthritis with my Crohn's and I also can't take NSAIDs or most of the other arthritis drugs. Voltaren does help me some, in some of my joints, but not always and not it all of my joints. It can sometimes feel like it's not just the joints, but the muscles, etc., so it is very confusing. I also had the bone scans and everything looked good. I hate to tell you, but I've been flaring since January and have been on prednisone since then. We can't seem to find something that is treating both without causing other side effects. You can ask about
taking injectable methotrexate...maybe your dr. can call that in. It really helped my joints, but my liver enzymes got too high and I had to stop it. I just switched from Humira to Cimzia and my arthritis is better but it seems my stomach is bothering me again...so I guess I get to pick the lesser of two evils...whichever one that is. Good luck.
