WOW, I am glad you found such a great doctor. I had a great doctor, and he retired last year. It's been 10 years, 3 ketamine infusions, meds, meds, meds, LDN, Sympathetic blocks, and finally SCS. The scs works kindof it just masks the pain, the way oxycontin does, makes me think of something else. I think I will try ketamine again. It worked for 2 weeks I was pain free! I was like a kid on Christmas morning, the world could not be more perfect. Then it came back.
