Introduction
Under normal circumstances, leg pain and knee pain in a 12-year-old child may be caused by growing pains, excessive exercise, knee ligament injury, patellar softening, or bowed legs. If discomfort occurs, timely medical consultation is recommended. It is also advised to maintain a balanced diet, ensure adequate sleep, engage in appropriate outdoor activities, and develop good living habits.
Generally, leg and knee pain in 12-year-olds may be caused by growing pains, overexertion, knee ligament injuries, genu varum (bowlegs), patellar softening, and other reasons. If discomfort occurs, timely medical consultation is recommended. Detailed explanations are as follows:
1. Growing Pains
During periods of rapid growth in children, inconsistent growth rates between leg muscles and bones may lead to muscle tension and pain. Applying heat, gentle massage, and moderate exercise can help alleviate growing pains.
2. Overexertion
Excessive physical activity or participation in sports can also cause leg and knee pain. This type of pain is typically activity-related and can be relieved with rest. It is important to reduce physical activity, allow appropriate rest, and use ice or heat compresses to reduce local inflammation.
3. Knee Ligament Injury
Intense physical activity may cause knee ligament injuries, leading to knee pain, swelling, functional impairment, and possibly a sensation of knee instability. Under a physician's guidance, immobilization with a cast and rehabilitation exercises may be required.
4. Genu Varum (Bowlegs)
Genu varum may result from imbalanced bone development, increasing stress on the knee joints and causing leg and knee pain. Abnormal leg posture becomes particularly noticeable when standing or walking. Corrective insoles or physical therapy may help address this condition.
5. Patellar Softening
Patellar softening may be caused by injury, leading to cartilage wear and flaking, which causes knee pain. It may also be accompanied by sounds during knee movement, a sense of instability, or a locking sensation. Under medical guidance, physical therapy, muscle-strengthening exercises, and use of knee braces can be beneficial.
It is recommended that children maintain a balanced diet, ensure adequate sleep, engage in appropriate outdoor activities, and develop healthy lifestyle habits.
