Julie,

You say the docs aren't sure why you have the neuropathy. Have they check out diabetes or impaired glucose intolerance with 2-hour oral glucose tolerance test and HgA1C blood work? The following should also be part of the regular neuro workup:

- Heavy metals test (lead, mercury, arsenic).
- B vitamins
- History of alcohol consumption
- EMG and skin biopsy for large- and small-fiber nerve damage.

Good luck....
