<s>[INST] My grandson is 19. About every 5 weeks he gets stomach pain right in the middle  above his belly button. It hurts when he takes deep breaths. Usually lasts 24 hours. Had a low grade temp tonight, was in bed 24 hours. Didnt vomit this time, but has  in the past. Feels better to lay on his side in a ball, not on his back. [/INST] Hi, It could be cholecystitis. I suggest he sees a doctor for liver function tests and have an ultrasound of the liver and gall bladder. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Anders Mark Christensen, General Surgeon </s>
