Question
A four-month-old infant develops a large hard lump on the right side of the neck when turning the head to the left, but it is not visible or palpable when the infant does not turn their head. What could be the cause?
Answer
Based on the description, this may be due to muscle fasciitis. It is recommended to undergo active treatment, including early massage, cold compress, and microwave therapy, as well as taking oral blood circulation and stasis medicine. It is suggested to bring the infant to the hospital for a detailed examination to determine the cause. At the same time, it is important to pay attention to proper feeding of the infant and encourage them to get plenty of sunlight exposure to promote health.
