Have you ever seen a football player come running off the field with one arm dangling by his side? Or maybe he might be shaking it like crazy, as if it is "asleep"? If so, there's a good chance he has a "stinger" injury, sometimes called a "burner". It happens when a bundle of nerves called the brachial plexus gets stretched, usually during a block or tackle when the shoulder gets pushed down and the players head is pushed simultaneously to the other side. In this photo the guy in red could get a stinger injury as his right shoulder is pressed downward and his head is pushed to the left.
... So, what to do about it?
