Your nerves carry information to and from the brain. They also carry signals to and from the spinal cord. You have many nerves outside of your spinal cord. They are all a part of your peripheral nervous system. They work with your brain and spinal cord. All of these parts give your body information about senses, moving, and the environment. Damage to any of the nerves outside of your brain or spinal cord is peripheral neuropathy. What you feel and where it is will depend on what nerves are affected.
