Burner / Stinger
There is a sudden onset of burning pain and/or numbness along the outside of the arm with associated arm weakness following a lateral flexion injury of the neck/head (e.g., lateral "whiplash"). The symptoms usually only last a couple of minutes.
"Burner" or "stinger" are the names given to injury of the brachial plexus or nerve roots caused by a lateral flexion injury. This is a common injury in sports and has a high percentage of underreporting (70%) because of the transient symptoms. In general, lateral flexion away from the involved side with accompanying shoulder distraction (depression) on the involved side causes a stretch on the brachial plexus. Varying degrees of injury may occur; however, the majority of injuries are mild, with transient symptoms.
