Small fiber neuropathy is a neurological condition that affects the small nerve fibers responsible for transmitting pain, temperature, and certain automatic body signals. These small fibers play a key role in how the body senses heat, cold, and discomfort, as well as in regulating functions such as sweating and blood flow. When these fibers are impaired, sensory experiences and physical sensations may change.

This article provides education-only, evergreen information to explain what small fiber neuropathy is, how it is commonly described, and how it may affect daily life. It does not provide medical advice, diagnosis, or treatment.
