Small fibre neuropathy is a disorder of the peripheral nervous system for which main clinical manifestation is chronic neuropathic pain, often accompanied by alterations of the autonomic nervous system. This disease affects the small diameter myelinated (Aδ) and non-myelinated nerve fibres (C). Its causes are primary or secondary, such as metabolism defects, infection, and autoimmune, neurological or toxic diseases, among others. Routine neurophysiological tests are usually negative. Diagnosis can be made with complementary tests which are difficult to access from Primary Health Care. These include microneurography, and the sensory stimulation test; but the most used technique is the skin biopsy. Treatment is directed at the causes and the neurological symptoms. Due to the variability of symptoms that can be presented, the importance of being aware of this condition is emphasised in order to reach a diagnosis and offer the appropriate treatment.
