My husband has suffered similar symptoms to you, in his left hand, due to an elbow injury, it has now spread to his left shoulder as well. We live in Australia & not many Dr.'s over here know very much about this condition. (RSD). Which is extremely frustrating, all I can do is sit & watch his hand go blue, & listen to him telling me how painfull & tingly his hand, elbow & shoulder are. We are currently under a neurologist, hopefully he can help, best of luck with this disease!!
