Small fiber neuropathy is often characterized by neuropathic pain in the feet with normal nerve conduction studies and neurologic examination. Diagnosis requires specialized nerve tests, including autonomic studies and a skin biopsy study showing reduced intraepidermal nerve fiber density. Small fiber neuropathy has numerous causes but is often idiopathic. A practical approach to identifying an underlying cause is to first screen for common ones and then proceed with further testing as needed. Treatment consists of correcting the underlying cause, managing pain, and modifying lifestyle.
