The stimulator seems to be the all rave these days. Be very careful about the SCS and since your doctor is sold on it lock stock and barrel be weary of him also. Some with RSD have relief, but all the reading I've done on the subject overtime it becomes a burden with those with RSD. It accentually masks the spread from the insertion of the device and overtime it catches up with you. Your doctor should know this because most with RSD do. Also, this device never was formally created or even researched to see that in fact this device should be recommended for a serious neurological condition especially one as painful as RSD. Keep looking into ketamine. Google is your friend. I'm sure many will chime in with places you can contact. I know that GW hospital in washington performs this but there are better ketamine treatment centers than GW. Check out both of these sites:
