Hi everyone. I'm not sure what's happening today but I have had seriously painful muscle seizures in my lower right arm which also distorted my hand as wrist twisted in weird position and fingers locked tight. Now I don't know if it's the pmr or that I have reduced preds from 15 to20 mgs today. I'm asking because I know many of you have suffered this disease for many years and may be able to advise me. It was quite frightening as it's never happened before.
