Question
What is the cause of frequent abdominal pain around the navel in a six-year-old child?
Answer
The patient is a six-year-old child who has been experiencing abdominal pain and vomiting for about ten days, with frequent nausea. There is no special medical history, and there has been no previous diagnosis or treatment. The physical examination did not reveal any abnormalities. The initial suspicion is that it may be related to umbilical inflammation, and the treatment methods include local application of 3% hydrogen peroxide solution and 75% alcohol cleaning, as well as applying 1-2% gentian violet. Improvement can be seen within a few days. If the condition is severe, medical attention should be sought promptly. Additionally, it may also be gastroenteritis, and it is necessary to confirm whether an abdominal ultrasound examination has been conducted.
