Question
A 4-year-old boy has recently been complaining of back pain, and his parents are seeking possible causes.
Answer
Back pain could be related to kidney or heart issues, or it may be due to overexertion, such as prolonged use of electronic devices. It is recommended to consult a doctor for cardiac ultrasound, urological ultrasound, and a series of rheumatoid disease checks. Additionally, it is advisable to avoid children playing computer games or using mobile phones for extended periods. Poor sleep posture may also lead to muscular imbalance in the back, such as using overly soft pillows or inappropriate sleeping positions. Further examination at a hospital can be arranged if necessary.
