I shattered my wrist approximately three years ago and had to have surgery. They repaired the damage with a metal plate and screws. However, recently I have begun to have unbearable pain that radiates in my arm and sometimes up to my neck. The pain comes and goes. Some people have told me it s due to the cold weather affecting the metal in my arm, where others have said my body may be rejecting it. Which theory is more likely and what treatment should I request? Where do I start?
