A "stinger" is an injury of the brachial plexus often seen in football players having sustained a hit forcefully stretching the head and neck. The brachial plexus is a group of nerves that exit the neck to provide sensation and movement to the arms. In the situation of a "stinger," these brachial plexus nerves are stretched beyond their normal limits causing temporary numbness and paralysis of the arm. In severe cases, like motorcycle accidents or high impact hits in football, this stretching injury can result in tearing (avulsion) of the nerves away from the spinal cord causing permanent damage and paralysis of the arm.
