Definitely seems as if small-fiber neuropathy, possibly due to metabolic syndrome--there's a much larger body of reserach evidence out there now than even a few years ago pointing to impaired glucose tolerance causing neural symptoms well before frank diabetes can be diagnosed--but yes, I am wondering from what you wrote how many of your symptoms may have another underlying etiology--and how many may have been exacerbated by medications.

It is interesting that you mention the gluten/celiac angle--gluten sensitivity can result in a very wide range of neural symptoms, including neuropathy and ataxia. And the current serological gold standard for celiac (that is, if an intestinal biopsy hasn't been done)--the anti-transglutaminase IgA test--seems to be correlated to some degree with the extent of villous damage of the intestine, so it often misses early stages. or those whose primary symptoms are neural rather than gastic.

I, and others, certainly have recommended that anyone with neural symptoms should cut down simple sugars and try a gluten-free trial--neither can hurt, and very often they seem to help (sugar and gluten are both neuroexcitatory and eliminating them may help damp down an overactive nervous system).

Don't know if you've posted at the neuropathy board, but it would be good to get some of the experts there to converse with you--if you want, you (or I) could do a cut and paste of your last post and let it be perused.
