Living With Peripheral Neuropathy
Peripheral neuropathy is not a single disease. It’s a general term for a series of disorders that result from damage to the body’s peripheral nervous system.
What is the Peripheral Nervous System (PNS)?
The body’s nervous system is made up of two parts. The central nervous system (CNS) includes the brain and the spinal cord. The peripheral nervous system (PNS) connects the nerves running from the brain and spinal cord to the rest of the body…the arms and hands, legs and feet, internal organs, joints and even the mouth, eyes, ears, nose, and skin.
Peripheral neuropathy occurs when nerves are damaged or destroyed and can’t send messages from the brain and spinal cord to the muscles, skin and other parts of the body.
Peripheral nerves go from the brain and spinal cord to the arms, hands, legs, and feet. When damage occurs, numbness and pain in these areas may occur.
Peripheral neuropathy can affect multiple nerves (polyneuropathy) or only one nerve or nerve group (mononeuropathy) at a time.
Mononeuropathy is usually the result of damage to a single nerve or nerve group by trauma, injury, local compression, prolonged pressure, or inflammation. Examples include:
Carpal tunnel syndrome (a painful wrist and hand disorder often associated with repetitive tasks on a computer keyboard)
Bell's palsy (a facial nerve disorder)
The majority of people, however, suffer from polyneuropathy, an umbrella term for damage involving many nerves at the same time.
