I suggest you consult with Dr. Carden in Marina Del Rey or research the pain clinic at USC, which Michael has highly recommended here on NT in the past.

Praeger will push for a spinal cord stimulator in all likelihood, and many of us that have gone to him for consults were unhappy with the experience... Just do some searches on patient reviews and you'll see what I mean.

Dr. Carden offers out patient Ketamine, as well as other blocks and the SCS (but isn't pushy about it at all!) If you're willing to go further south there is also Dr. Sajben in La Jolla.
