^Agreed. SFN means there is no electrical evidence of a neuropathy but you have all the symptoms of neuropathy.
They tested your hypoglossus? They stuck a needle under your chin into your tongue? (Did it hurt?)
The changes you referred to can happen with age (over 40...there I said it). On EMG they look like bunching up of muscle fibers of shorter height. Repeating the test, with the same doc preferably, could be helpful for diagnosis in 6 to 12 months. SFN testing can be performed with sweat testing, temperature measurements or skin and/or nerve biopsy. I think those tests are the best out there for SFN, but still have a degree of false negative results.
