There can be many causes of shoulder pain, one of which is a brachial plexus injury. The brachial plexus is a collection of nerves that originate in the neck and shoulder region and control movement and sensation in the arm, hand, and fingers. A brachial plexus injury occurs when these nerves are damaged or torn, often as a result of trauma to the shoulder or neck.
