You might want to search fmichael's posts about SCS.

You also need to understand that doctors have a huge financial incentive to do this procedure. While I think there are other health conditions/disorders where the SCS can have a long term health benefit, I'm not convinced that the risk is worth it for most CRPS patients. While it is true that those that have a positive experience carry on with their lives and aren't actively posting on NT or similar websites, I've read enough posts about spread and problems a few years after, that I'm just not willing to risk it at this point. For someone that hasn't tried other options first, especially Ketamine infusions, I would certainly suggest starting there first. --If you can afford to go out of pocket for some HBOT sessions, that might be worthwhile as well.
