Growing pains in children are recurrent episodes of intermittent pain in both lower extremities, especially in the lower legs, knee joints and their surrounding areas. The peak age of onset of growing pains is 3-6 years for boys and 3-8 years for girls. Typical “growing pains” in children occur in the evening or at night and last for a few minutes or two hours and then resolve on their own. When painful, there is no local redness or swelling, no obvious pain, and normal passive movement of lower limbs. When it is not painful, there is no discomfort and it does not affect daytime activities. The main factor of “growing pains” in children may be the asymmetry of lower limb torsion and foot torsion, but as children grow older and develop, the clinical manifestations of growing pains will be significantly reduced or eliminated. In clinical practice, we should exclude cases of unequal lower extremities, flat feet, pars plana, osteochondroma, etc. Parents should pay attention to the rest of the child and avoid cold. Parents should pay attention to the child’s rest and avoid cold. They can give the child a gentle local massage and apply ointment suitable for children. If the pain cannot be relieved by itself or even becomes more and more severe, the child should go to the hospital in time.
