Small Fiber is just a form of neuropathy. It is peripheral as well. There are other forms that affect the large fibers and motor function. Small fiber usually results in pain, burning, tingling, buzzing, numbness, etc. You also might want to look up autonomic neuropathy which can cause some of the other issues you mentioned.
Have you had extensive blood work done? Testing for diabetes, thyroid, toxicity, vitamin levels, autoimmune issues, etc. ? That would be essential now that you have a confirmed diagnosis. A good neuro will want to search for the cause of SFN, once its diagnosed. A skin biopsy is pretty accurate in diagnosis SFN.
