I had my RSD spread into my back after a lumbar sympathetic block last January. From there is went into my neck, down my arms, into my hands, to my sides, my chest, and stomach. After this spread I started to experience a whole lot of symptoms which included the full body spasms, loss of balance and coordination, nausea, blurry/double vision, and a whole laundry list of other things. What other types of things have you had since it spread? Just the body spasms or other things too? We tried a lot of different things to get all this under control...lots of trial and error. Maybe one of the things I tried could help you...
