A burner, also called a stinger, is a common injury in contact sports, especially football. The exact mechanism of the injury is not well understood, but a burner is thought to be due to either stretch or compression, or a combination of both, of the brachial plexus. The brachial plexus is a network of nerves that has just exited the spinal cord. These nerves travel across the shoulder and into the arm. Symptoms of a burner are sudden pain and tingling extending from the neck and down the arm into the fingers.
