I believe that my PMR was triggered by the Covid vaccine since the symptoms came on shortly after I got the shot. I initially thought I had just done too much gardening and dismissed the pain and lack of mobility. It was a number of months before I figured out what I had and saw my doctor but looking back I saw the connection between the shot and symptoms. The previous fall, 2020, after I got my flu shot I spiked a fever for 6 days straight. I thought I had Covid but did not. Throughout my adult life I have had strong reactions to the flu shot. I worked in health care and needed to get the shot every year. About 50% of the time I would feel ill for a couple of days so always got my shot on a Friday so I would not have to work if I reacted poorly. I believe that I have had low level immune system problems for a long time but the Covid vaccine was the final straw. I am not getting any vaccines for the near future.
