It’s been a long time since diagnosed. Prednisone for 8 months and weened off it and during that time I had X-rays, ultrasounds and MRIs of shoulders, hips, knees. After all that a new doc said knees aren’t associated with PMR and I’m feeling better so maybe it wasn’t that. In any case, I now take daily (2) 200 mg ibuprofen after breakfast and plenty of water. I’m no doctor but I wonder if it had anything to do with Covid.
