What growing pains typically look like and when they happen
If your child only complains that their legs hurt at bedtime—but they're running around perfectly during the day—it may not be what you think.
Parents often worry that nighttime leg pain means something serious, but many children experience what's commonly called growing pains.
Despite the name, we don't actually know that they're caused by growth. What we do know is that they're common in young children, especially between the ages of about 3 and 12.
Growing pains usually happen in the evening or at night, often after an active day. They're typically felt in both legs—especially the calves, thighs, around the knees—and they're gone by morning.
Kids with growing pains don't limp. They don't have swollen joints. And they're able to run, jump, and play normally during the day.
Gentle massage, stretching, a warm heating pad, or an age-appropriate dose of pain medicine if needed can often help them feel better.
But here's when it's worth calling your pediatrician.
If the pain is only in one leg, causes a limp, wakes your child every single night, comes with swelling, redness, fever, weight loss, or continues into the daytime, that's not a typical pattern for growing pains and deserves a closer look.
Most growing pains are completely harmless—but knowing what is and isn't normal can help parents know when to seek medical advice.
