Cervical Sports Injuries: The Stinger
How does a stinger happen?
A stinger is caused by a stretching of the brachial plexus nerves. These are
peripheral nerves that exit the spinal cord and run across the shoulders, under
the collarbone, and into the arms. The brachial plexus nerves are responsible
for giving the arms their strength and sensation. As a result of a forcible
sideways blow to the head or a blow to the shoulder itself, these nerves may
become compressed, stretched, and irritated.
What are the symptoms of a stinger?
A side collision of this type causes immediate and intense pain, as well as
a tingling or burning sensation in the neck that runs down the arm to the fingers.
Weakness in the affected arm or hand is also common. The weakness, numbness,
or tingling sensations may last as briefly as a few minutes or as long as a
few weeks.
How is a stinger treated?
Most stinger injuries resolve on their own after a period of rest. Athletes
are usually removed from the sport until symtpoms are gone. Ice packs on the
neck or shoulders, anti-inflammatory medications, massage, and neck strengthening
exercises are often part of the treatement plan. Players can usually return
to their sport once the pain is gone and they have regained full range of motion,
strength, and normal sensation in the neck and arms. Persistant or recurrent
symptoms may indicate a more serious injury. Neck x-rays, a CT scan, or MRI
may be necessary to rule out other serious conditions with similar symptoms.
How can a stinger be prevented?
Strengthening neck muscles are an important way for athletes to prevent stingers.
Using good technique in contact sports and avoiding spearing (head down tackling)
is also important. Safety equipment such as neck rolls that limit backward movement
of the neck may also help.
Most importantly, players who experience symptoms of a stinger should immediately report them to their coaches or team physician despite the risk of being removed from the game. Ignoring or playing through a stinger can lead to more serious injuries.
