Thanks everyone for all the advice. Tessa, I never even heard of that epidural option, one doctor I had spoken with mentioned using ketamine in an epidural but my insurance would not cover it because it was totally experimental. I am just not sure what to do. One other complicating factor for me is the fibromyalgia. One doctor told me the neurostimulator will make it worse. Now this new doctor says that is not true. I don't remember if I mentioned this but I had a test dose of ketamine during a nerver block and it really helped my fibromyalgia as well as RSD. That one dose gave me almost a full week with much reduced pain.
