I went to Duke neurology in Durham,NC - long derive with overnight stay traveling from way out in western North Carolina mountains. My chief complaint was the onset of peripheral neuropathy over the past months. They did the "EMG" and said "Yes, you have small fiber neuropathy. We don't treat that. You need to find a rheumatologist. Good bye."
The "EMG" is an electromyogram, which measures conductivity of the nerves - in this case the arms and legs. My neuropathy symptoms came up quickly earlier this year: tingling and pain in the arms and legs accompanied by muscle pain in the arms and legs.
This was a long, all day drive across the state of North Carolina for a thirty minute test. Overnight hotel was needed. I did not do my research in advance. I wrongly thought neurologists treat neuropathy. I was wrong. They do not.
