--is it possible to post what was said in the skin biopsy report, including the intraepidermal reference ranges?

Form what you just posted, it sounds to me like there may be evidence of a nerve degeneative process, but often, doctors not really versed in this only look at the reference ranges for nerve fiber density, which were originally codified at Johns Hopkins and sort of arbitrarly designated as "abnormal" only below the firth percentile and above the ninety-fifth percentile, and while this may make sense from a statistical standpoint, there may be other morphological evidence there--comments on the condition of the nerves, whether there is swelling, overbranching, etc.--that might point to an "abnormal" results.

The idea that you should have another in 12 months certainly sounds like there is some evidence of SOMETHING going on.

Also, where was this report produced from? (I don't trust the pathology findings from places where this is not done regularly--and that sort of limits it to Hopkins, Cornell-Weill, Jack Miller, UCSF, Mass General, Jacksonville Shands, maybe a few others).
