Small-fiber neuropathy and fibromyalgia

Information on small fiber neuropathy

Your nerves are composed of cells call neurons connected by fibers called axons. The axons or fibers found in the skin, organs and other peripheral nerves are referred to as C fibers or small fibers. The fibers provide information such as pain and temperature sensations from the skin as well as maintaining automatic functions such as regulating heart rate, breathing and body temperature. Damage to the nerves themselves is called peripheral neuropathy and this can sometimes be a comorbid condition with fibromyalgia. Now within those fibers are a bundle of smaller strands bundled together with a casing. Some of the smaller bundles have a protective a casing called a myelin sheath and are called ‘myelinated’ while others do not and are refered to as ‘unmylinated’. It is the unmylinated bundles that appear to be damaged with fibromayglia and indeed according to the Pain Management and Rehabilitation Center in Chicago it is also the case for small fiber neuropathy itself.

The symptoms of small fiber neuropathy are “numbness, and annoying or painful sensations, called paresthesias, that are variably described as tingling, stinging, burning, freezing, itching, aching, pulling, squeezing, or electric shock-like. Innocuous stimuli can provoke unpleasant sensations, called dysesthesias; Clothes can feel like sandpaper against the skin, the hands may become hypersensitive to touch, or pressure from shoes or socks can causes severe pain in the feet. Symptoms of small fiber neuropathy can occur anywhere in the body, including the arms, legs, torso, face, or even the mouth.” painrehabcenterThese sorts of symptoms are familiar to fibromyalgia and would account for fibromaylgia pain moving around the body. Lyrica and Cymbalta can be used to treat small fiber neuropathy which can account for why some people see a positive result with those medications.
