Dear MD, My 11-year-old daughter complains of pain for 3 day. The pain is around the bottom of the left rib cage. it is tender, and sore kind of pain, but persistent, intensity 3-4 out of 10, worsen when pressing on the area, and when she moves from lying position to sitting up. She does not have any trauma, no fever, no nausea or vomiting, no diarrhea, clear lung sound. Thank you, Kathy
