Another option might be to take a short course of steroids and see if that helps the pain. Sometimes a steroid taper will calm things down for me and then I don't have to switch biologics.
Another option might be dose escalation. In psoriasis, Enbrel is given at higher doses - 50 mg twice a week for 3 months. You could try that. I have done that with every single biologic I have been on - escalated the dose or frequency before moving on to something else.
You could also add an NSAID if you aren't already on one.
