My husband has had RSD since a work injury (police officer) in 1987. The injury and RSD was originally in his right hand, but has now spread into his shoulder, back and left arm. He is an avid runner - runs every day - and that is how he deals with the pain. Just wondering if anyone has ever experienced this - recently, after long runs, he has what he calls a "spell" - begins about an hour after the run - usually starts with a dry mouth, then progresses into a severe exacerbation of the RSD - arm feels like it's on fire, extreme pain, he gets pale, sweats profusely, severe diarrhea. It takes several hours to recover. Anyone ever experience anything like this?
