Oddly enough, it may well be coincidence because PMR is a "sudden emergence" condition. Frustrating not to be able to tie down the "lose ends" but although the triggers for PMR are not identified, it's emergence pattern is well established (so says my research and my doctor). It comes on literally overnight and can grow in intensity over a period of hours or days, case depending. One day you're feeling the age you always were -- the next day you're at least 82 and feeling more enfeebled by the minute.
I, myself, have been very suspicious of my PMR being the result of a senior flu shot since it began 2-3 days following the shot, last Novmber. However, I've read and studied and thought more about it, and I really can't make a direct connection (though in some ways that would be satisfying). Because the Covid shots and the flu shots introduce a very specific viral target, they are not capable (theoretically) of being able to trigger a wide-spreading immune response -- which is what PMR is believed to be. This is the data the pro-vaccine folk understand and rely on. The rest of us, who struggle with PMR which appeared subsequent to "a jab" of one sort or another, are left wondering. The trouble is that PMR has historically "simply appeared" without identified causation, so for many of us at this point in time at least, it's proximity to "vaccination" is part of our history, but not necessarily or even likely to be connected.
I'm sorry you are having to deal with this miserable condition and I have been where you are - wondering about connections with shots. Certainly I am leary of taking more "vaccinations" for flu I've never contracted in the past. I think I'd trade getting the flu for up-to-5-years-of-PMR any day. And COVID shots? No relation to PMR in my experience, but people are unique and the territory is uncharted as we sail through it. I wish you the very best in care and recovery, friend.

Mine started suddenly overnight 10 days after my second jab. But when I think about it my neck gave me huge problems all summer after the first jab in May. I believe there is a direct connection and also, 2 other people I know have been diagnosed with PMR over the last month, which probably coincides with their jabs too. Booster? Not me...not yet. Not until this settles down. It has taken 5 months to get a diagnosis, prednisone is working and I'm not messing that up. I have never had a flu vax of any kind and I'm 72. PMR makes me feel my age, otherwise I'm still 40. LOL.
