Hi,
I read your email and thought I would point you to a book by Daniel Haley "Politics in Healing" that I just bought a week ago.
In it, there is a reference to RSD and that one person was actually "cured" of RSD with the use of electromedicine that was developed by Dr. Becker. (page 310) Info can be found at www.alpha-stim.com
Hopefully it could bring some relief.
Good Luck and I hope your girlfriend feels better soon.
Kate
