Small Fiber Neuropathy Symptoms

Small fiber neuropathy is a type of nerve damage that affects the tiny nerves under your skin that sense heat and cold, causing a number of uncomfortable symptoms.

Causes

• Possible causes of small fiber neuropathy include diabetes, HIV, genetics and drug or alcohol abuse, according to Phoenix Neurological Associates. In some cases, the cause of small fiber neuropathy symptoms is unknown.

Types of Symptoms

• Symptoms of small fiber neuropathy include reduced sensitivity to heat and coldness and severe pain. It is also possible to have a delayed or diminished reaction to pain caused by physical damage to the affected area, such as the feelings you experience when you step on something sharp.

Features

• The pain caused by small fiber neuropathy is described as burning, jabbing, stabbing and prickling, reports the Colorado Neurological Institute. Some patients experience a feeling that resembles an electric shock, while others describe the sensation as an intense pressure.

Location

• Small fiber neuropathy is most common in the feet, but it is also possible to experience symptoms in your legs or hands.

Treatment

• There is no cure for the symptoms of small fiber neuropathy. When the condition is caused by diabetes or substance abuse, reducing blood sugar or use of drugs and alcohol often improves symptoms, while in others antiseizure medications, narcotic pain relievers and antidepressants may alleviate pain.
