[Growing Pains : Cause, Significance and Treatment]

Background: Leg pain is a common reason for consultation in the children's orthopedic clinic. It can occur across all age groups, although most patients are of pre-school or elementary school age. As there are a series of possibly severe differential diagnoses that might cause such pains in children and adolescents apart from benign pains that occur in the context of growth, a thorough patient history and physical examination are essential.

Pathogenesis: Despite extensive research, the cause of benign growing pains has not been elucidated so far. Several possible factors play a role on an anatomical, metabolic or functional basis, ; thus, various theories exist with regard to their origin.

Diagnosis: Growing pains constitute a diagnosis of exclusion. If a possible organic cause of the pains is suspected, an extended diagnosis of the person affected should be made. Growing pains primarily occur at night and are always self-resolving.

Therapy: With regard to treatment, mild pain medications can be employed in more severely affected patients. It is much more important to inform family members about the benign nature of the condition. Reassuring words and physical relaxation exercises, in addition to massaging and stretching of the leg muscles, can cause a significant reduction in pain without medication.
