VI: Diseases of the nervous system

G50-G59: Nerve, nerve root and plexus disorders

Nerve, nerve root, and plexus disorders encompass a range of conditions that affect the peripheral nerves, which carry signals between your brain and the rest of your body. These disorders may result from illness, injury, or a congenital abnormality. Common symptoms include muscle weakness, numbness or tingling, and pain, which can range from mild to severe. The progression of these conditions varies, as some may remain static while others gradually worsen. In some cases, these disorders may lead to problems with movement or sensation. While nerve, nerve root, and plexus disorders can affect any part of your body, they often impact the hands, feet, arms, or legs.
