<s>[INST] Daughter is age 13 having gas bubble type pain under both sides just under her ribs. She said when she bends over the left side pain moves down in bottom of her tummy. Gave her gas relief pills. Shes sleeping now. Should I worry or is this probably gas? [/INST] Hello! Thank you for asking on Chat Doctor! I understand your concern and would explain that her symptoms seem to be related to dyspepsia (troubles with indigestion) and the accumulation of gas in her intestine, leading to a distension of the diaphragm and pain in this region. A gastric disorder (gastritis or gastroesophageal reflux) can't be excluded. The fact that her symptoms are modulated by the body movement is another argument in favor of these disorders, including possible musculoskeletal pain. If her symptoms persist, I recommend consulting with the GP for a careful physical examination, a chest x-ray, an abdominal ultrasound and some lab tests (complete blood count, kidney and liver function tests, fasting glucose, blood electrolytes) to rule out any other disorders related to this symptomatology.  A fibrogastroscopy may be necessary to exclude possible gastroesophageal reflux. Hope to have been of help! Best wishes,  </s>
