StillTrying, My wife has RSD and I always keep my eyes and ears open to something that will help her. One ray of hope is to check out "LostMary" posts. The post I provided is her latest post. If you do a search on her through this site you'll see her progression before and after the pump. My wife has tried several treatments with no luck but the pump is very interesting indeed.
