Small fiber peripheral neuropathy is a type of peripheral neuropathy that occurs from damage to the small unmyelinated peripheral nerve fibers. These fibers, categorized as C fibers, are present in skin, peripheral nerves, and organs.〔(Overview of Small Fiber Neuropathy ). Therapath Pathology.〕 The role of these nerves is to innervate the skin (''somatic fibers'') and help control autonomic function (''autonomic fibers''). It is estimated that 15-20 million people in the United States suffer from some form of peripheral neuropathy.〔Zhou, Lan (2000). (Small fiber neuropathy: A burning problem ) ''Cleveland Clinic Journal of Medicine'', vol.76 5.〕 == Symptoms == Sensory symptoms of small fiber neuropathy are highly variable. Common complaints include paresthesias, dysesthesias, and insensitivity to pain. ''Paresthesias'' are abnormal sensations. They are often described as numbness, burning, cold, prickling, pins and needles along with other symptoms. ''Dysesthesias'' are unpleasant sensations, either spontaneous or evoked. A light breeze, the feeling of clothes, or even a soft touch can cause pain.〔Latov, Norman. ''Peripheral neuropathy: when the numbness, weakness, and pain wont stop''. American Academy of Neurology (AAN) quality of life guides, 2007, p.8.〕 Insensitivity to pain can be particular problem. One may be bleeding or have a skin injury without even knowing it.
