Question
Doctor, my 4-year-old often cries and has knee pain before bedtime. How should it be treated?
Answer
It is recommended that you bring your child to the hospital for a specific examination to determine the cause. Common causes of lower back pain include lumbar spondylosis, lumbar disc herniation, and nerve compression. Joint pain could be due to catching a cold or nerve compression. Pay attention to not catching a cold, avoid staying in one position for too long, and engage in moderate activity, balancing work and rest. Pay attention to joint warmth, and do not let your child be exposed to wind or contact with anything. Consider calcium supplementation for a period of time and observe after getting more sunlight.
