When should you treat a sports injury yourself, and when should you stop playing until you see a physician? Here are a few sports injuries that you should know about.

Head injuries/concussions

Don't take chances with a concussion or any other head injury.

The brain is composed of tissue with the consistency of gelatin and is normally cushioned by spinal fluid. A concussion occurs when the brain knocks against the bony surface of the skull. Injuries that can occur to the brain in a concussion are bruising, tearing blood vessels, stretching nerve fibers and increase in the pressure inside the skull as a result of bleeding or swelling. In a concussion, normal brain function is affected.

Concussions can be caused by a blow to the head or by a rapid deceleration that causes the brain to slosh inside the skull. According to the Centers for Disease Control and Prevention (CDC), 1.6 million to 3.8 million concussions due to sports- and recreation-related activities occur each year.

The American Association of Neurological Surgeons (AANS) says that about 300,000 concussions occur each year in high school, college, and professional football players and that the risk of concussion in football is three to six times higher in players who have had a previous concussion.

In most cases, concussions do not cause a loss of consciousness. One concussion does not usually cause permanent damage, but the AANS warns that there is no such thing as a "mild concussion."

A health care provider should always be consulted, especially if any of these symptoms occur:

  • Unconsciousness
  • Headache
  • Vision disturbance
  • Dizziness
  • Loss of balance
  • Confusion
  • Memory loss
  • Ringing ears
  • Nausea or vomiting
  • Difficulty in concentrating

Symptoms in adults that require immediate medical attention:

  • Headaches that get worse
  • Weakness, numbness or decreased coordination
  • Repeated vomiting
  • Cannot be awakened
  • Have one pupil -- the black part in the middle of the eye -- larger than the other
  • Convulsions or seizures
  • Slurred speech
  • Getting more and more confused, restless or agitated

Symptoms in children that require immediate medical attention:

  • Any of the danger signs for adults (see above)
  • Child won't stop crying
  • Child can't be consoled
  • Child won't nurse or eat

Post-concussion syndrome can occur to people who suffer a head injury. They may have poor memory and concentration, headache, fatigue and dizziness for weeks or months after the injury. In children who have even a moderate concussion, there may be an increase in irritability, angry behavior and meanness for up to a year. The AANS recommends that athletes not return to play while they have these symptoms and that those who have had repeated concussions should consider ending participation in that sport.

Neck injuries

The neck supports the head and is very flexible, so many injuries to the neck occur from a fall or an abrupt jerking of the head (whiplash). Neck pain can be caused by strains, sprains or fractures. Strains and sprains are injuries to the muscles and ligaments. Pain can also come from injury to nerves that branch from the neck into the arms and hands. The action that injures a neck does not have to be sudden. Injury can occur over a period of time from activities that strain the neck such as mountain bike riding and horseback riding.

Symptoms that indicate medical attention is necessary:

  • Neck pain after an injury; if the pain is severe, the person should not be moved and emergency medical personnel should be called
  • Pain or numbness radiating down an arm, or weakness in an arm
  • Pain that continues for a period of time

If severe neck pain occurs after an injury, such as in a motor vehicle accident, diving accident or fall, a trained professional, such as a paramedic, should immobilize the person to avoid the risk of further injury and possible paralysis. Seek immediate medical care.
