I have RSD in my right leg.. from my lower back all the way through my toes. My middle toe on my foot curls under my foot when walking, but thats the only "disforming" thing i have if you would consider it that. I get swelling in my right leg in random areas, especially around the butt cheek (right butt cheek droops alot lower then the left).

I have lumbar sympathetic blocks, and they help me tremendously. Its like a new me. They KILL my back.. but my leg pain going away, and for long periods of time, with flare ups, but not as bad as without the block.

Doens't it block the nerve signals to the brain that tell ur brain you are in pain.. so u don't feel it as much?? I believe that is how it works.. good luck!
