Can you tell us the results of your tests to this point (if you are comfortable doing that)?

Neuropathy has so many potential causes the work-ups are often long and expensive, assuming you can find a doctor willing to be as comprehensive as needed, and not always fruitful (many do end up being idiopathic). And symptoms them stem from the central nervous system--brain and spinal cord--can absolutely mimic those that come from peripheral nerve.

Still, two big sources of information you should be aware of--

The Liza Jane spreadsheets, designed to be about as comprehensive a database as could be regarding testing for neurological symptoms (and a great way to track results/patterns of testing over time):

The Gluten File--linked here in our gluten forum--the most comprehenisve database on the subject now extant, including much information about neurological manifestations of gluten sensitivity/celiac:
