I know there is a hospital in St. Lukes Presbyterian in Denver, Colorado. that has a chamber. Perhaps there website would have some information on the benefits? My doctor wasn't aware of the benefits/risks for RSD patients so I havent' spent much time researching the area. What I have read though it doesn't seem to have long lasting results.
My theory at this point is the less invasive the better. I also have pain levels off the chart constantly. Nothing but rest brings releif, and even then sometimes the rest if more like torture, just laying there me and the pain.
I hope you are able to find some relief soon. If you are able to find any additional information please post!
