Research Stellate Ganglion Blocks. You want someone to perform right before surgery. I suggest they don't do it blind. If the doc has you help pinpoint the best response you'll likely get a better response.
I had CTS performed prior to RSD onset, and have not had the cupitel tunnel surgery performed (sp?) and won't. In the scheme of things I don't believe it's worth the risk for me and several RSD docs and surgeons have agreed.
Get 2nd and 3rd opinions from RSD knowledgable docs.
