For symptoms of a mild concussion, observation at home is usually enough. This may indicate a neck or spinal cord injury. Do not move the person. Call 911 or your local emergency number. The person is disoriented and unable to answer simple questions for more than a few minutes after the injury.
Symptoms persist more than a few hours.
It is important to observe and interact with the person after the injury to make sure that mild symptoms get better and that additional ones do not develop. If symptoms do not clear up or they get worse, get medical help. A concussion usually is self-healing, and little or no treatment is necessary. Rest and avoiding activities that put a person at risk for another head injury or require vigorous movement and concentration should promote recovery within a few days. You may also take a pain reliever such as acetaminophen as recommended by your doctor.
