Growing pains: Growing pains are pain symptoms relatively common in children ages 3–12.  Typically, they are located in the muscles, rather than the joints, of the leg and less commonly the arm.  They are usually felt on both sides, and appear late in the day or at night, waking the child, with pain varying from mild to very severe.  Pain is absent by the morning, and there are no objective clinical signs of inflammation.  Pain can recur nightly or be absent for days to months.  Growing pain is not associated with other serious disease and usually resolves by late childhood, but frequent episodes are capable of having a substantial effect on the life of the child.  Growing pains were first described as such in 1823 by a French doctor.
