I just responded to someone who asked how long some of us have had PMR. But, now, I need to respond here too! I am positive my PMR came after the 2nd Moderna shot. After I found my way to a Rheumatologist 4 months later I was told I had PMR and started on Prednisone. 2 months later I was in my PCP office for a check up. I had been in the hospital for a round of serious divverticulitis and treated for it (while on the steroid so my immune system was down). 18 days of IV antibiotics and I was in for an outpatient follow up. My doctor said did I want a flu shot. I NEVER get them but decided I felt so vulnerable after the PMR and quick and serious infection that maybe I didn't want the flu. MISTAKE!!!!! I got the quadravalent flu shot for Seniors. I was sick for 3 days with fevers and fatigue and felt generally awful. Then I started having night sweats drenching the bed and clothes, then shivering chills. I had a fever of up to 101 for 10 days. My sed rate and crp and wbc were all up. Back to the hospital. No one sure what was up. Fast forward. In December I was with my kids in CT as I was seeing my oncologist who treated my pancreatic cancer in 2016 (I was given 2 months to live and I am alive and well from that 6 years lagter!!!). He is a great diagnositition and so many things were OFF iun my blood work with my sed rate greater than 130 that I flew from cA to CT to see him. I was there 6 months. Covid was raging then. I was with grandkids in their home...they were getting it and being sequestered. So I got the booster. OMG. Mistake. I did not get Covid...but the vax's (all of them) I am sure sent me down this hell river. I am good now after 19 months and on 2 mg Medrol. SED rate and cRP normal now. So, the moral of this story...is YES THE VACCINES AND FLU SHOTS for some of us are a disaster. NEver again for me. Microbe1943
