When I had mine, I was carefully told that there is no other out patient procedure that carries higher risk than nerve blocks. While I'm only speaking for myself, I can only tell you that I screamed during the process. Because of my chest hitting the x-ray table so hard over and over again, after my 2nd one I was bruised pretty darn bad over a large part of my upper chest. These are no walks in the park.

As far as results, the first one lasted 2 weeks and the 2nd one lasted less than a week. Because it was Worker's Comp, even though my specialist had ordered 6 total, they decided they'd only pay for 2. Who knows, this might have been the only time Worker's Comp actually did something good for me.

I have known of other people who have had very good results by getting the entire series at the very early onset of RSD so while I'm saying mine were pure hell, I do know they can make a difference. It's just the process that will kill you - but they can change things long term, so with caution I'd say go for it, but hang on tight. You're going to be sore afterward. Bob.
