Injury to the nerves of the neck and shoulder that cause a burning or stinging feeling are called burners or stingers. Another name for this type of nerve injury is brachial plexus injury. Football players are affected most often. Up to half of all college football players have had at least one burner or stinger. Many of these occurred during high school football. Fortunately, it’s not a serious neck injury.

What parts of the body are involved?
The nerves leave the spinal cord, go through the neck, under the clavicle (collar bone) and armpit, and then down the arm.
The brachial plexus begins with five roots that merge or join together to form three trunks.
The three trunks are upper (C5-C6), middle (C7), and lower (C8-T1). Each trunk then splits in two, to form six divisions. These divisions then regroup to become three cords (posterior, lateral, and medial).
Finally, there are branches that result in three nerves to the skin and muscles of the arm and hand: the median, ulnar, and radial nerves.
What causes this condition?
In the process, the brachial plexus between the neck and shoulder gets stretched. The same injury can happen if a downward force hits the collarbone directly. In football, burners or stingers occur most often when you tackle or block another player. This motion overstretches the nerves of the brachial plexus.
It’s not clear exactly where in the brachial plexus the damage occurs. Some experts suggest the injury is most likely to be at the level of the trunks, rather than at the nerve root level. The results of other studies show that burners or stingers from compression forces cause nerve root damage while traction injuries result in plexus injuries. A nerve root injury would be much more serious than a burner or stinger from a trunk injury of the brachial plexus.
Other athletes who participate in wrestling, gymnastics, snow skiing, and martial arts can also experience burners or stingers. Some studies suggest that athletes with a narrow cervical canal may be at increased risk for this type of injury.
What does this condition feel like?
The shoulder and arm may feel numb or weak. You may feel as if this area is tingling. Weakness may be present at the time of the injury. Some patients report the arm feels and appears to be dead. This paralysis and other symptoms may be transient or temporary. They may only last a few seconds or minutes. But for some patients, healing takes days or weeks. In rare cases, the damage can be permanent.
How do doctors diagnose the condition?
X-rays, MRI, and electrodiagnostic studies such as an electromyogram (EMG) can help make the final diagnosis. The EMG will confirm a problem, pinpoint the area of damage, and give an idea of how long recovery will take for each individual.
What treatment options are available?
Protecting the neck with a soft collar is the first step in the acute phase of burners or stingers. If the injury occurs on the playing field, the player is placed in a protective collar before being moved off the field. This is worn until X-rays are taken to rule out fracture, dislocation, or other more serious neck injury.
Rest and gentle neck and shoulder range of motion are advised until symptoms resolve. If this does not occur within a few days, then physical therapy may be needed. Your therapist will use modalities such as biofeedback, electrical nerve stimulation, and manual therapy to help restore the natural function of the nerves.
Range of motion and strengthening exercises will be added as tolerated. Posture is very important during the healing phase. A chest-out position helps open the spinal canal, thus giving more room for the spinal cord. This posture also decreases pressure on the nerve roots. Your therapist will provide sport-specific therapy when the symptoms resolve (go away).
Surgery is not a treatment option for burners or stingers. Management remains conservative (nonsurgical). Patients are followed through the athletic season until recovery is complete.
What should I expect following treatment?
Burners and stingers are self-limiting. This means that with treatment, they will resolve over time. You will likely be able to return to full sports participation when you no longer have any symptoms. Full neck and shoulder motion must be present. And you should be able to participate in practice without any problems before entering a game.
It is possible to get another burner or stinger but it could be something more serious. If you experience these types of symptoms again, slowly lie down on the ground. Wait for the team trainer or physician to examine you before moving your head and neck.
Some football players choose to wear extra padding, special shoulder pads, or a neck roll to protect the neck and avoid reinjury. All equipment should be in good condition and fit properly. Daily stretching of the neck is advised. Players should avoid using spearing or head tackling, which has been prohibited since 1979.
