Hi - I have been to a derm and 2 Rheums and was finally diagnosed yesterday w/PsA. I have the HL27 marker, and some joint damage in my feet and sacroiliac joints. The Rheum wants to start me on methotrexate and a biologic at the same time. He wasn't very good at discussing my concerns re: side effects and didn't give me info on why 2 drugs to start.
