Hi dear, Is he having any other symptoms like vomiting, abdominal distension , loose stools or constipation? Any relation to food intake? Any difficulty or pain during urination? How was his interest in schools before? Abdominal pain severe enough to cause school absenteeism, that too for 1 week need to be evaluated for the underlying cause. Less commonly, a stressful or unfavourable school environment also cause such symptom in adolescents. So kindly take him to his pediatrician for evaluation. Depending on associated symtpoms and findings on examination, you may be asked for few blood tests or ultrasound. Meanwhile give him paracetamol for pain relief. Hope I have answered your query Let me know if I can assist you further Dr Muhammed Aslam, Paediatrician
