What causes leg pain in children?

Leg pain in children may result from overuse-related muscle soreness due to excessive running or jumping, or it may be caused by localized pathological conditions such as musculoskeletal tumors or inflammation. In cases of excessive physical activity, leg pain is typically due to overworked muscles. Children's bones are not as strong as those of adults, and intense physical activity can lead to muscle pain. Localized diseases, such as musculoskeletal tumors or inflammatory conditions, can also cause pain; therefore, it is important to observe whether there are any visible abnormalities in the affected area. Additionally, children grow rapidly and have high nutritional demands. Insufficient calcium intake may lead to calcium deficiency, reducing bone strength and increasing excitability of muscles and ligaments, which can result in lower limb muscle spasms and cause symptoms of leg pain.
