I am wondering if the members on the Peripheral Neuropathy and also on the RSD forums here at NeuroTalk may have some insights for you.
the PN forum is at
http://neurotalk.psychcentral.com/forumdisplay.php?f=20
and RSD is here
http://neurotalk.psychcentral.com/forumdisplay.php?f=21
hoping you find answers and effective treatments.
browse around the rest of the community too...help can sometimes come in unexpected places I have learned.
