I was on Humira but wasn't getting enough coverage for the arthritis. I have AS but also went into a Crohn's-related arthritis flare, so I was switched to Remicade because the dosing is more adjustable. Methotrexate was added in, as well. Though it may seem that your joint pain is from the Humira, perhaps it is a change in your systemic condition. Best of luck and I hope you feel better.
