Anyone know of a doc that actually knows what RSD is & knows how to treat it in Western WA. state???

I'm really looking for a doc to do a Sympathetic Nerve Block. I saw one & instead he did a Epidural & has made my mild RSD spread badly!!
My GP nor my podiatrist don't know of any of doc that know RSD & do SNBs I really need to get something done to help get it back in control as I had had for the last 22 years!!!
