<s>[INST] My daughters upper stomach has been hurting since this morning. It has gotten worse throughout the day. She is shaking, seems to have a fever( out if town do not have a thermometer with us) . She s laying in bed and says it hurts to move around to turn over and makes it hard to breath. She threw up once yesterday after eating nachos from a gas station and felt fine after that. Any idea what could be going on? [/INST] Hi,thank you for providing the brief history of your daughter.As she is having pain in the upper quadrant of the abdomen, this could be related to the acidity issue. Also, vomiting frequently is the indication for the indigestion and there is nothing to worry as kids body learns to act and react the improper food. Getting a thorough examination by the pediatrician and taking proper medication for the acidity should help reduce the symptoms.Also, having a good life style and slow frequent eating with lots of water should help her to ease the pain.RegardsJay Indravadan Patel </s>
