In medicine, a stinger,〔http://orthoinfo.aaos.org/topic.cfm?topic=A00027〕 also called a ''burner'' or ''nerve pinch injury'', is a neurological injury suffered by athletes, mostly in high-contact sports such as ice hockey, rugby, American football, and wrestling. The spine injury is characterized by a shooting or stinging pain that travels down one arm, followed by numbness and weakness. Many athletes in contact sports have suffered stingers, but they are often unreported to medical professionals. Anyone who experiences significant trauma to his or her head or neck needs immediate medical evaluation for the possibility of a spinal injury. In fact, it's safest to assume that trauma victims have a spinal injury until proven otherwise because: * The time between injury and treatment can be critical in determining the extent of complications and the amount of recovery * A serious spinal injury isn't always immediately obvious. If it isn't recognized, more severe injury may occur * Numbness or paralysis may develop immediately or come on gradually as bleeding or swelling occurs in or around the spinal cord〔http://www.mayoclinic.org/diseases-conditions/spinal-cord-injury/basics/symptoms/con-20023837〕 == Mechanism == A stinger is an injury that is caused by restriction of the nerve supply to the upper extremity via the brachial plexus. The brachial plexus is formed by the anterior rami of the nerves at the 5th cervical level of the spinal cord all the way to the nerves at the 1st thoracic level of the spinal cord. The brachial plexus innervates the upper extremity as well as some muscles in the neck and shoulder.〔Saladin, Kenneth S. Anatomy & Physiology: The Unity of Form and Function. 6th ed.
