--given the range of symptoms you are experiencing, it is unlikely you have a neuropathy that is just affecting the small fibers; the small, unmyelinated nerve fibers control the sensations of pain and temperature as well as many autonomic functions, but you are also experiencing motor/muscular symptoms. That implies disruption of the larger, myelinated fibers as well, which may be peripheral or may come from spinal or nerve root compression.

Often, the symptoms of problems in the spinal area can be exactly mimicked by those of a more systemic peripheral neuropathy, which is why the hunt for cause may be long, expensive, and have a lot of dead ends. But take a look at the following, and compare the work-up and tests you've had to these, which are designed to be very comprehensive for neural symptoms:
