Peripheral neuropathy is a result of damage to your peripheral nerve, which may be a result from traumatic injuries, infections, metabolic problems, inherited causes and exposure to toxins. One of the most common causes is diabetes mellitus. The peripheral nervous system sends information from your brain and spinal cord (central nervous system) to the rest of your body.
Peripheral neuropathy often causes weakness, numbness and pain, usually in your hands and feet. It can also affect other areas of your body. People with peripheral neuropathy generally describe the pain as stabbing, burning or tingling. In many cases, symptoms improve, especially if caused by a treatable condition. Medications can reduce the pain of peripheral neuropathy.
