Thank-you! In addition to my joint symptoms, I had these strange skin lesions, purpura, in, of all places, my groin and my eyelids. I went to a dermatologist, who did skin biopsies, came back Amyloidosis. That sent me on a journey to find an Amyloid specialist, at the Cleveland Clinic, who did a barrage of testing that also found Multiple Myeloma. Both are rare, incurable but treatable, and can mimic PMR and/or RA symptoms. Unfortunately, I had symptoms and un/misdiagnosed for over a year before actual diagnosis, allowing it to worsen. But...I am confident I can, hopefully, achieve a long-term remission. My hope is that other folks and physicians are aware of this as a possibile differential diagnosis.
