Mine was a little different since it was for my right foot (I believe it was a lumbar sympathetic block), but my first 2 did nothing and the third one actually caused a flare up that was excruciating! Of course, the doctor didn't know what to say when I was crying in pain, except for "well you must not have RSD because otherwise it would have worked." The more people I talk to the more I realize that it doesn't always work. I decided to stop doing them. I get questioned by doctors all the time to do them again, but I just have this feeling inside of me that says I know my body better than they do and my body doesn't want to do any more. I know exactly how you feel about not knowing what to do, and I wish I had the right answer, but I'll be rooting for you whatever you decide!
