I have come to the conclusion that my PMR was triggered by covid. Last November I went on a bus trip to New England with a friend who had what appeared to be a cold. She assured me that she had tested negative for covid, but within five days I had the same "cold." By the end of the week, I had pain in one arm and my pelvic girdle. In retrospect, I also lost my sense of taste and smell. Apologies to the fine people in New England, but I complained that their food had no taste! When I returned home, my doctor immediately diagnosed PMR, and I have been tapering down prednisone ever since. I'm wondering if anyone else has had the same experience?
