My right wrist has been extremely painful for over a month. My symptoms seem to be a match for deQuervain s (Painful thumb, wrist, about 2 inches above my wrist, and occasionally extending to my elbow). I have a brace that provides some relief, but returns with a vengeance if I remove the brace. I m newly retired, and on Medicare. I don t yet fully understand Medicare A/B, but I don t find any reference to my concern on the government website. What should I do?
