An injury to the brachial plexus can cause a burner or stinger. This often happens when the head is forcefully pushed sideways and down. This bends the neck and pinches the surrounding nerves.
Contact sports. Athletes who engage in contact sports are more likely to suffer a burner or stinger. In fact, up to 70 percent of all college football players report having experienced a burner or stinger during their 4-year careers.
Burners and stingers often occur with a fall onto the head, such as in a wrestling takedown or a football tackle. In fact, tackling or blocking in American football is the athletic activity that most often causes burners or stingers. Football defensive players and linemen frequently suffer this injury.
Spinal stenosis. In addition to playing contact sports, a small spinal canal may put you at greater risk for a burner or stinger. Athletes with recurrent stingers or burners may have smaller spinal canals than players who do not suffer recurrent injury. This condition is called spinal stenosis.
