Hi @sdenver, My PMR is in remission and I had both Pfizer vaccine shots earlier this year with only the normal minimal side effects, the worst being the extreme fatigue the day after my second vaccine shot. I posted a few reference links earlier in this discussion on influenza vaccines and PMR which may provide some insight. Here is the link to the post - https://connect.mayoclinic.org/comment/331519/.

Have you discussed the symptoms with your doctor?
