Hi, Since there is no relief with the OTC medicines the cause has to be found out. The probable causes in a 9 year old girl can be as follows: * Constitutional disease such as typhoid * Viral infection * Local abdominal problem like gastroenteritis, lymph node enlargement * Sore throat can be viral or bacterial causing swallowing of infected material causing stomach ache Hence, I would advise her the following: * Consult a pediatrician for clinical examination * Investigations of blood, urine and stool * Ultrasound of abdomen All these will lead to a proper diagnosis and hence will have specific treatment. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. T. Chandrakant, General Surgeon
