I just came back from my appointment and I didn't get much information out of the neurologist, surprise, surprise... He told me I had benign fasciculations which were causing the twitches, not PN. I pressed him so I could bring back some info for you guys and IF I understood him he said twitches were a sensory symptom and that thin fibers caused the burning and thick fibers caused all the other sensory symptoms. Not sure I follow that. Maybe MrsD can make sense of it.
