I am 76. Newly PMR diagnosed 2 weeks ago or so. Sudden onset (March 13) of belly distress AND pain in back muscles that evolved to pains in shoulders, neck, trapezius muscles, wrists, elbows, hips when lying on them; inability to underess with arms overhead, reach for things in fridge or cabinet, or get off the toilet without using hands to lift up...causing more pain in wrists! I got the 2nd MODERNA vax on Feb 26,2021. So 15 days later this sudden onset of symptoms. I was sick for 3 days with the 2nd dose...fever, profound fatigue. SO, of course we don't know...if the vax generated this or not. But, it is, to me suspicious. Not provable. Now on 10 mg prednisone to start. Helping about 80% and I can reach, turn over without groaining, get up from sitting position without assistance. Muscles for 12-14 hours good. After that not as good. Will try dividing the dose AM/PM to see. Sharon
