Symptoms

Signs and symptoms of a brachial plexus injury can vary greatly, depending on the severity and location of your 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 your arm
• Numbness and weakness in your 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 injure 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 your hand, arm or shoulder
• Complete lack of movement and feeling in your arm, including your shoulder and hand
• Severe pain

When to see a doctor

Brachial plexus injuries can cause permanent weakness or disability. Even if yours seems minor, you may need medical care. See your doctor if you have:

• Recurrent burners and stingers
• Weakness in your hand or arm
• Neck pain
• Symptoms in both arms
