Growing Pains

Last Modified: June 24, 2026

Growing pains are leg pains that some kids have at night. Despite the name, they are not really caused by growth. Here’s how to recognize growing pains and help your child feel better.

What are growing pains?

Growing pains are muscle aches and pain that often1, 2:

  • Affect both legs. Sometimes arms may ache too.

  • Do not involve the bones or joints

  • Can be mild or severe

  • Can cause a child to wake up during the night

  • Are gone by morning

  • Don’t happen every day. There can be days, weeks, or months between episodes

What causes growing pains?3

Despite the name, growing pains aren’t actually caused by your child growing. Pediatricians aren’t sure what causes them, but one idea is that growing pains may occur after children play or exercise harder than usual. They don’t feel pain when doing the activity, but might feel pain or soreness later.
