Growing pains are often described as an ache or throb in the legs — often in the front of the thighs, the calves or behind the knees. Growing pains tend to affect both legs and occur at night, and may even wake a child from sleep.
Although these pains are called growing pains, there's no evidence that growth hurts. Growing pains may be linked to a lowered pain threshold or, in some cases, to psychological issues.
There's no specific treatment for growing pains. You can make your child more comfortable by putting a warm heating pad on the sore muscles and massaging them.
