Right after I got my Flu vaccine I got PMR. It has been 4 1/2 yrs, and had to retire from work. I took the covid vaccine to go on a cruise and I was unable to walk within an hour of getting the first vaccine. Had to take a prednisone dosing starting with 3 days at 80mgs. It did improve but it will be a slow process back to normal. I got the 2nd covid vaccine 4 weeks later and PMR symptoms were increased in back and arms took 10mgs of Prednisone for 3 days then back down to 5mgs and I have not titrated down yet as the symptoms are still very present. I have just started taking PEMF (pulse electro magnetic field) treatments They have helped a great deal the first 3 consecutively!
