<s>[INST] My daughter who is 9 has been complaining for 2 days that her stomach hurts. Sometimes it is worse then other. She is not running a fever. She is eating just not as much. She says that her right side hurts the most but her left does also just not as bad. Now her back is hurting [/INST] Hi. Thanks for your query. Noted the history related to your 9-year-old daughter having pain in abdomen for 2 days, no fever, right side hurts more than the left and there is back pain. The most probable causes of such a pain can be colitis, abdominal lymph node enlargement, worms and so on. I would advise her the following in such a situation:Send sample of stool, blood and urine. Clinical evaluation by a Pediatric or General Surgeon. Dewormin. Antibiotic and metronidazole if there is evidence of infection. Ultrasonography of the abdomen. This should help her to get a proper diagnosis and treatment. </s>
