Polyneuropathy is the most common form of peripheral neuropathy, a condition involving damage to the peripheral nerves — which are outside the brain and spinal cord — and the symptoms that result from that damage. In this form of neuropathy, multiple nerves are affected, and frequently, nerves throughout the body will be affected simultaneously.
The symptoms of neuropathic pain tend to be similar across a wide range of causes, says Vernon Williams, MD, a sports neurologist who is the director of the center for sports neurology and pain medicine at Cedars-Sinai Kerlan-Jobe Institute in Los Angeles.
