Nerves carry messages to and from the brain to allow you to move and feel. Nerve injuries range from compression of the nerve (such as carpal tunnel syndrome) to a complete laceration or cut of the nerve and its surrounding sheath. Damage to a nerve can affect your ability to use your muscles and your ability to feel (sensation). Nerves that are compressed or stretched may respond to conservative treatment. If a nerve is completely cut, surgery will be necessary to restore function. (See Nerve Repair.)
