For whatever it's worth, if I lived close enough to a good peripheral neuropathy center such as the one Dr. Smith suggested, would have gone to it.

But as I live in the Greater Cleveland area, my neuro is at the Cleveland Clinic. I'd give her a good grade, and the testing I had was not 100% but a lot of causes were tested for. Among the tests were a spinal tap and paraneoplastic panel that was sent to Mayo Clinic.
