I was dx w/FM approx 3 years ago. Since that time, it seems that a new symptom happens everday. That maybe a slight exaggeration but not that far away from the truth As I as scratching my back with a back scratcher, my arm locked up and I became unable to move my fingers. It was like my arm and my hands were in a charlie horse, it was painful. Reumatologist dx me with palindromic syndrome. Has anyone else experienced this and is it also a part of FM?
