Velkyn,

I am a nurse too and was also hurt at work. RSD is a horrible condition, but Workman's Comp is living hell. I feel for you as my five year plan was crushed too.

As far as a Bier block, I believe they usually use a blood pressure cuff as a tourniquet. I haven't read anything supporting the use of a bier block to treat CRPS, but putting a tourniquet on a CRPS limb does not sound like a good idea.

I encourage you to keep searching for a good PM doc. I'm on my 4th one and finally found someone who really knows CRPS and can think outside of the box. I have done several brachial plexus blocks and they really have helped.
