I believe the pfizer documents recently released make it clear that with every additional shot the risk of adverse reactions increases disproportionately. I got the first shot over a year ago, no problem; and after the second, a persistent inflammation. It began to abate and then I got the booster and the inflammatory reaction grew worse. I have needed prednisone to manage it. I am not getting any more Pfizer shots.
Is it arthritic inflammation? You might want to get on hcq for that.
