Hope your pain goes away and stays away. I contracted PMR after my second COVID vaccination in 2021. It took me a about a year to taper off of prednisone and I've been in remission since Dec. 2022. I, personally, will never get another mRNA vaccination. I know it triggered my PMR.
BTW, I haven't been vaccinated for the past 3 years and had 2 bouts of COVID since then. The first one involved a 2-day fever and lasted about a week. The second bout was last month and was much milder--scratchy throat, lethargy, and a head cold. These are milder symptoms that many of my friends have experienced and they've been vaccinated multiple times. Is this a true vaccine when everyone can still contract COVID and spread it to others?
I feel that your best defense is a good offense. Check out the other threads on this forum that talk about an anti-inflammatory diet. I follow a whole foods, organic, primarily plant-based diet, high in anti-inflammatory foods.
