Small Fiber Neuropathy May Cause Fibromyalgia Pain

A small study has linked the pain of fibromyalgia to small nerve fiber neuropathy, which is painful damage to a certain part of a certain nerve. This could be a ground-breaking study, as fibromyalgia has previously been linked to nerve dysfunction, but not to actual nerve damage.

Researchers examined the small fibers in different areas of the body using three different methods: sensory testing, pain response, and skin biopsy.

They determined that people with fibromyalgia had:

  • Impaired small fiber function that lead to increased temperature sensitivity;
