I have lost over 10% body weight in last four months. I'm mostly skin and bones. Also low fever and night sweats. Is this a symptom of PsA ? Have an appointment with Rheumatologist next Tuesday. I've been on an elimination diet that functional Dr put me on for two months. I don't think it should be causing this drastic weight loss. I'm down to 147#s from low 160's. Don't know how to stop the loss. Any help?
