Dennis, Had compressed nerve in arm causing RSD and had surgery to decompress nerve(they didnt know at time of surgery that it was RSD too). At 1year they realized i had RSD and had stellate ganglion blocks-4-5. Had SCS trial but got stim in whole body and feared causing spread of RSD. Read a lot of pros and cons of SCS. Unfortunately, i now at 2years have full body RSD. momof4
