Why do three-year-old children always say their knee hurts?

Patient's question:

In the afternoon to evening, it appears every few days, and it is often used during periods of high activity.

Doctor's answer:

Analysis of the condition: Children aged 3 to 12 experience rapid height growth and quick bone development, while the growth of their surrounding nerves, tendons, and muscles is relatively slower, which can lead to tractional pain. Additionally, if children engage in excessive daytime activities for prolonged periods, their muscles may easily become fatigued and painful. Excessive activity can also cause the accumulation of acidic metabolic byproducts, such as lactic acid, leading to muscle soreness.
Advice: It is highly likely that the pain is due to growing pains. The most important thing is to rest promptly. Avoid overexertion. Appropriately supplement with calcium and oral vitamin C. Apply warm compresses with a water heater at night. If necessary, non-steroidal anti-inflammatory drugs can be used. There will be no long-term consequences or impact on the child's normal growth and development. However, first ensure that it is not possible that the condition is rheumatic fever or bursitis.
