Most minor head injuries improve with rest and observation. Your doctor may choose to observe you in the hospital or may send you home under the care of a responsible adult. The doctor will give this person specific instructions about watching for danger signs.
Headache and neck pains can be treated with over-the-counter pain relievers, such as acetaminophen (Tylenol and other brand names). If you have more severe pain, your doctor may give you a prescription pain reliever.
