I highly recommend Cleveland Clinic. I was diagnosed with SFN at the beginning of COVID in 2020. My Dr. at CC was excellent; she called me since I couldn't keep my appt bc of COVID and she diagnosed me over the phone, however, I did go the the Clinic for tests to determine for sure it was SFN. I am having a terrible time finding a good neurologist so basically I have been untreated for the last 3 years. I did have one Dr. that prescribed gabapentin. I have an appt this month to see a new Dr. Btw, the neurologist that diagnosed me was Julia Bucklan at Cleveland Clinic. She is wonderful When she called me; she stayed on the phone with me for an hour asking many questions to determine what was wrong with me.
