The brachial plexus is a complex of nerves that originates in the spinal cord and branches out through the neck to the shoulder, arm, and hand. Injury or disease of the brachial plexus nerves can severely impair the function of the shoulder, arm, and/or hand.
Symptoms may include a limp or paralyzed arm, lack of muscle control and/or a lack of feeling or sensation in the arm, hand, or wrist.
Treatment begins with modification of activities that may be contributing to the symptoms. Immobilization and/or non-steroidal anti-inflammatory medications may be prescribed. Steroid injections may relieve symptoms. Surgery may be recommended for people that have progressive symptoms or weakness that does not respond to conservative treatment.
