Correction: the Neurologist did both the Epidermal nerve density and the sweat gland nerve density tests, (I just got the bill, another $650)
On the calf, the epidermal nerve count was normal, but with the swaet gland nerve density is was low normal, by just one point. The sweat gland nerve density would signal Autonomic small fiber neuropathy. I was going to ask him about the sweat test, but I guess this is similar.
Has anyone gotten this done?it is a fairly new test, I don't think it is fully recognized as a "gold standard"yet.
