Hi thank you. Yes I ws talking about nerve block shots. I had 2 in my ankle but none in my back but the pain doc felt they wouldn't work so why I needed the scs. When I was at cleveland the dr convigton said though I too don't have edema or some other symptoms of rsd mine is very similar to it. Also how important it is to be on my legs so they don't atrophy. Depending I'm either going to see another rsd pain doc or wait for the reumo to see about myofacial etc. I'm so sorry for al your going through too. If I can help support you in any way. I know very little in the diseases. Im a weird case too cause my age and history. Good luck.
