Thanks for all your help everyone.

His arm has been spasming for the past few months - He has muscle relaxants for that - His leg (the one that had the RSD) used to spasm and still did occasionally but this today is both of his legs, toes curling, ankles unmovable and this going on in both legs. Even the one without the RSD.

He's had another episode today and his legs are very weak........He's barley able to make it to the bathroom. Not sure what the heck is going on but we're getting ahold of the doctor tomorrow.
