If you were diagnosed with small fiber sensory neuropathy via skin punch biopsy, then that diagnosis is correct. That is the gold standard for diagnosing it. EMG does not find it. Mine started with the feeling of having a bad sunburn in many areas at once.

But you might also have large fiber and/or other issues causing those other types of pains you mentioned. Small fiber will produce sticking pain (as in needles), tingling sensations, hyperanalgesia, burning pains and allodynia (I have that, too) and maybe other things. Whether or not it produces pneumatic drill type pain I don't know.

Thought I'd answer and describe how non-length dependent SFSN has affected me in case you weren't altogether aware of the various types of sensations it can produce.
