Are achy legs keeping your child awake at night? He or she may have growing pains.

Growing pains are cramping, achy muscle pains that some preschoolers and preteens feel in both legs. The pain usually occurs in the late afternoon or evenings. But it may cause your child to wake up in the middle of the night.

Growing pains usually start in early childhood, around age 3 or 4. They tend to strike again in kids aged 8-12.

Causes of Growing Pains

Despite the name "growing pains," there is no firm evidence that growing pains are linked to growth spurts.

Instead, growing pains may simply be muscle aches due to intense childhood activities that can wear your child's muscles out. These activities include running, jumping, and climbing. Growing pains seem to be more common after a kid has a particularly full day of sports.

Symptoms of Growing Pains

Growing pains are different for everyone. Some kids have a lot of pain, others do not. Most kids do not have pain every day.

Growing pains can come and go. They may be experienced for months or even years. Most kids outgrow growing pains within a few years.

The pain is usually felt in the late afternoon and evening, right before dinner time, and at bedtime. The leg pains may hurt so much that they may wake your child from sleep.

If your child seems perfectly fine in the morning, don't be quick to think he or she was faking. Growing pains disappear in the morning. They usually do not interfere with the child's ability to play sports or be active.

In general, growing pains are felt in both legs, especially in the front of the thighs, back of legs (calves), or behind the knees.

Studies suggest that children who have growing pains may be more sensitive to pain. Children who have growing pains are also more likely to have headaches and abdominal pain.

How Are Growing Pains Diagnosed?

A doctor can usually diagnose growing pains by examining your child and asking questions about his or her medical history and symptoms. It is important to rule out any other possible causes of the pain before making the diagnosis of growing pains. This is why it is important to see the doctor if you think your child has growing pains or any limb pain.

If your child has growing pains, the doctor will not see anything abnormal during the physical exam. Blood work and X-rays are usually not needed in this case.
