In general, athletically induced peripheral nerve injuries are difficult to diagnose, particularly if pain is the initial complaint rather than weakness or sensory disturbance. The stinger is probably the most common yet least understood peripheral nerve injury that occurs in sports. This is a peripheral nerve injury, not a spinal cord injury, despite the frequent misuse of the term stinger to describe the burning hands that often are associated with the central cord syndrome.¹
