Small Fiber Neuropathy Symptoms

Small-fiber neuropathy (SFN) is a peripheral nerve disease that most commonly presents in middle-aged and older people. The symptoms are insensitivity to heat and/or cold, tingling, numbness, muscle weakness, cramps, pain, and other symptoms. People describe the pain as an ice pick being poked into bone, like an electric shock, or walking on broken glass. Sometimes the pain causes a loss in the ability to feel when injury occurs, so one may be bleeding or have a skin injury and not even know it. SFN does not conform to the typical stocking-glove distribution, and may even involve the face or the trunk.
