Question
A three-year-old child often complains of knee joint pain in winter, and a doctor has diagnosed it as growth pain, suggesting the use of an oral liquid containing zinc and calcium. However, now a seven-year-old child still frequently feels pain during the autumn and winter seasons. How can one determine if this pain is still growth pain, and whether other medications are needed?
Answer
This pain may be caused by calcium deficiency. Some children who grow rapidly may experience joint pain symptoms. It is recommended to supplement calcium for the child regularly and drink more bone broth. Please note that the above content is a formatted example output based on the provided information.
