Peripheral neuropathy is a set of symptoms caused by damage to the peripheral nerves. These nerves are in parts of the body beyond the brain and spinal cord. The condition often affects the arms or legs. It causes a change in physical feeling. Symptoms include weakness in the muscles, tingling, numbness, or shooting pains. Symptoms may be more common at night. Your skin may be extra sensitive to light touch or temperature changes.
Peripheral neuropathy may be caused by:
- Complications from a chronic disease, such as diabetes
- Infections caused by viruses or bacteria
- Autoimmune disorders
- Cancer
- Chemo medicines to treat cancer
- Injuries
A lack of certain vitamins may also lead to it. It may also be caused by exposure to certain illegal drugs or chemicals. Several forms of neuropathy run in families (hereditary).
