Burners and Stingers
A burner or stinger is an extremely painful injury to the nerve supply in the neck or shoulder, commonly sustained in contact sports. Nerves originate in the spinal canal. Nerve fibers travel in bundles, with smaller bundles branching off main bundles to innervate more distant parts of the body. The nerves responsible for transmitting information to and from the arm leave the spinal canal between the vertebrae (spinal bones) in the neck. They group together into a network called the brachial plexus that branches out under the collarbone before travelling into the shoulder, and then down the arm and into the hand and fingers.
