Do you know how they test for small fiber neuropathy? I had an EMG for neuropathy but it was normal. I have severe nerve pain in both feet. Would an EMG show small fiber neuropathy?

Small fiber neuropathy is tested by a neurologist using a skin punch biopsy usually on calf/ankle and at upper thigh. This is gold standard. It shows microscopically damage to small fibers and number of small fibers compared to population.

Have you ever had cervical or lumbar spine MRIs to see if you have any spinal cord/nerve root compression/neurogenic claudication? This could affect nerves that go to legs/feet. EMGs only test nerve health in arms/legs (large fibers). Did your neurologist do a neuropathy blood panel to see what shows up as a vitamin deficiency or toxicity? Do you have diabetes or drink alcohol or smoke? Have you ever been tested for iron deficiency or thyroid dysfunction?
