<s>[INST] my 11 year old son woke up last night screaming in pain clutching his abdominal area. He described the pain as a sharp/ripping pain when moving or taking deep breaths. This morning he seems to be feeling better although the pain persists. The pain is isolated now only to the upper right side under the lower ribcage. Should I be worried? [/INST] Hi,If there is no other associated symptoms like fever, cough or breathing difficulty, we need not worry now. Just give him simple analgesics like paracetamol 2-3 times a day for 2 days. If the pain persists, or the above said symptoms appear, kindly take him to doctor for further evaluation.Take care. Hope I have answered your question. Let me know if I can assist you further.
