The cause of growing pains is unknown. But there's no evidence that a child's growth is painful. And growing pains don't usually happen where growth is occurring or during times of rapid growth. It's been suggested that growing pains may be linked to restless legs syndrome. But muscle pain at night from overuse during the day is thought to be the most likely cause of growing pains. Overuse from activities such as running, climbing and jumping can be hard on a child's musculoskeletal system.
