Definition of Growing pains

Growing pains: Mysterious pains in growing children, usually in the legs, likely occurring as a result of overuse. Growing pains are typically somewhat diffuse, and they are not associated with physical changes of the area, such as swelling or redness. The pains are usually easily relieved by massage, acetaminophen, or rest. If pain persists for over a week or there are physical changes, the child should be seen by a physician.
