--who know peripheral neuropathy, THE place for the most compehensive work-up and analysis, as Gumby alludes to, is the Cornell-Weill Center for Peripheral Neuropathy on Madison Avenue.

Cornell-Weill is affiliated with the Columbia Presbyterian health system, can draw on all its resources, and it is run by Dr. Norman Latov, who is one of the best known neuropathy researchers worldwide. All the docs there are also researchers, and they are very up on current research in the field, including he use of skin biopsy for small-fiber neuropathy, IVIg treatment, nutritional causes (celiac/gluten sensitivity, vitamin deficiency), and the like.

Also, the docs there are not quite typical neurologists (they will actually talk to you); the nature of the practice means they can spend more time in a visit than most practices can, and they do not seem to mind knowledgable patients.
