Types of nerve damage


Types of nerve damage
A cross section of spine (on left) shows how nerve roots are connected to the spinal cord. The most severe type of nerve injury is an avulsion (A), where the nerve roots are torn away from the spinal cord. Less severe injuries involve a stretching (B) of the nerve fibers or a rupture (C), where the nerve is torn into two pieces.

Signs and symptoms of a brachial plexus injury can vary greatly, depending on the severity and location of the injury. Usually only one arm is affected. Less-severe injuries Minor damage often occurs during contact sports, such as football or wrestling, when the brachial plexus nerves get stretched or compressed. These are called stingers or burners, and can produce the following symptoms: 
A feeling like an electric shock or a burning sensation shooting down the arm
Numbness and weakness in the arm
 These symptoms usually last only a few seconds or minutes, but in some people the symptoms may linger for days or longer. More-severe injuries More-severe symptoms result from injuries that seriously hurt or even tear or rupture the nerves. The most serious brachial plexus injury occurs when the nerve root is torn from the spinal cord. Signs and symptoms of more-severe injuries can include: 
Weakness or inability to use certain muscles in the hand, arm or shoulder
Complete lack of movement and feeling in the arm, including the shoulder and hand
Severe pain
