Burners (also called stingers) are injuries to the nerve network that provides feeling and muscle control in the shoulder, arm, forearm, hand, and fingers. The medical name for burners is brachial plexus injuries. They are common sports injuries. Most go away pretty quickly.
What Happens in a Burner?
The brachial plexus nerve network begins with nerve roots at the spinal cord in the neck and reaches to the armpit. Nerves branch out from there and continue down the arm to the forearm, hand, and fingers.
When a strong force increases the angle between the neck and shoulders, the brachial plexus nerves might stretch or tear. The injury may also pull the nerve roots of the brachial plexus from the spinal cord. Damaged nerves conduct sensation poorly and weaken muscle movements.
What Are the Signs & Symptoms of a Burner?
Someone with a burner may complain of:
pain or an electric shock shooting down the arm
numbness in the arm or fingers
clumsiness or weakness in the hand or arm
a warm sensation in the affected area
A severe injury may cause paralysis (loss of movement) of the arm and a loss of sensation.
