I am a physician, four and five years ago I’ve got PMR about a month after the flu shot in November, the last couple years I got a flu shot and did not get PMR, in January I got the Pfizer vaccine and six weeks later I had PMR flare muscle in my legs and had trouble walking in pain at night, prednisone taper over two months and I’ve been fine since, I know this is an anecdotal report but for myself I am convinced that vaccines have triggered a relapse in my PMR several times
