Trauma to the hand or wrist is the most common cause of nerve injuries. Damage to the nerve or nerve ending is often the result of the hand or wrist being cut, crushed, burned, or overstretched. Nerve damage may also arise due to illness or malnutrition.

Common symptoms of nerve damage include weakness, twitching, nerve pain, numbness, and a limited range of motion or the inability to move the hand or wrist.
