I contracted a mild case of PMR soon after my second Pfizer vaccination. I only hurt when laying down! I was extremely healthy until then, having had probably just one cold in over 25 years. Also, never got the flu, despite never havining a flu shot. I did get a mild case of COVID (2-day fever), but it was over a year since I had had that vaccination and it did trigger a bout of PMR again, but I was able to taper off of the 2 mg. dose in a few months. I am against ever getting another mRNA vaccine again in my lifetime. I believe that the J&J vaccine was not an mRNA one, so you might be better off with that one versus Pfizer or Moderna. I have yet to do any research on the J&J and PMR, but I also haven't heard of anyone on this forum that thought their J&J triggered PMR, or am I mistaken?
I may get the Shingrix vaccine, but I probably still have some protection from the old vaccine that I had just prior to Shingrix coming out.
