“Growing pains” is a harmless condition of unknown cause that affects 10 percent to 20 percent of growing children. It’s somewhat more common in girls. Despite the name, growing pains:
- Do not occur during the time of most rapid growth, such as the adolescent growth spurt.
- Do not occur at specific sites of growth.
- Do not affect the growth of children who have them.
- Occur in children 3 to 12 years of age.
About one-third of children with growing pains also experience other forms of recurrent pain, such as headaches or abdominal pain.
