What can i do to treat psoriatic arthritis?

See your doctor.: A rheumatology referral may be necessary, but a nsaid, with sulfasalazine and Methotrexate given once weekly are my first treatments. The biologics work (enbrel, humira, (adalimumab) remicade) work, but are quite expensive, not generic, require prior authorization, and almost always require prior Methotrexate therapy. Leflunomide, azothioprine, and Cyclosporine are options, given by someone in rheumatology!
