I was diagnoised w/RA six years ago, recently my rheumotoligist made a surprising comment that she did not think I had RA but would not make further comments or studies to see what else may be causing the joint pain in knees, ankles feet, neck etc. My hematoligist suggested I may have PSA, is that possible without psoraisis??? I do have on occassion a rash that comes and goes. Started about two years ago and drs do not seem to know what it is. Does anyone have any thoughts on this. My internist is looking into having a second opinion from another rheumotogist. Thank youView Thread
