What is Small Fiber Sensory Neuropathy?

Small fiber neuropathy (SFN), or peripheral sensory neuropathy, affects small caliber nerve fibers. Patients who have this disease most often experience tingling, burning, or numbness in the arms, legs, or feet.

Patients may also experience sensitivity to temperature (heat or cold) and/or automatic dysfunction.

Causes of SFN

Common causes of SFN include: diabetes, HIV, alcohol or drug abuse, and use of neurotoxic agents. Often, the cause of SFN is unknown.
