Just wanted to chime in. You can have small fiber neuropathy, and have normal tests for the above. I feel vibration fine, heat and cold fine, etc, and my sweat test came back totally normal.
I do, however, have the small fiber neuropathy symptoms (non length dependent, burning, shooting, numbness, pressure pain-they all wax and wane), and my two punch biopsies came back with significantly low nerve fiber density, and I was finally able to get diagnosed. So I think the biopsy is really the only sure fire way to know.
