Hi Bob, That can actually happen, can get worse with blocks and Stimulus. Can go to other parts of body. Do lots of research, LOTS. READ READ READ. Read lots of threads on this forum. Even if you should decide to go forward with some treatment, you have choice of hospitals with experienced RSD Drs. in other states or maybe even your own state. There are many Drs. out there that have no clue what RSD is, some willing to learn, some after they learn don't what to have anything to do with treating it, and come very good scients and excellent Drs. with good records. But we are all different,even our reaction to meds. I'll write you more later. Take care, loretta
