Peripheral neuropathy is a problem with the nerves that carry information to and from the brain and spinal cord to the rest of the body. This can produce pain, loss of sensation, and an inability to control muscles.
The symptoms depend on which type of nerve is affected. The three main types of nerves are:
One set of peripheral nerves relays information from your central nervous system to muscles and other organs. A second set relays information from your skin, joints, and other organs back to your central nervous system.
Peripheral neuropathy means these nerves don't work properly. Peripheral neuropathy may involve damage to a single nerve or nerve group (mono neuropathy), or it may affect multiple nerves (poly neuropathy).
There are many reasons for nerves to malfunction. In many cases, no cause can be found.
Peripheral neuropathy is very common. Because there are many types and causes of neuropathy and doctors don't always agree on the definition, the exact incidence is not known.
Some people are more likely to inherit neuropathy.
