I have small nerve fiber. I had the EMG done by neurologist. I also had my biopsy done by the neurologist also. They are seeing me for my SNF. That sounded rude the way the Dr handled it. My Dr sent me to neuro. I have heard of people going to the rheumatologist but I go to neuro. They do treat people with neuropathy. Mine came in March this year I woke up with full blown pin pricks. I would have been very angry to do what you did then get blown off like that. I have a lot of patience I really do but that one thing would have made me lose it.
