good morning. since the doctors have examined him and found nothing wrong, i feel that theres nothing serious with ur child, it may be just a severe abdominal cramps which is causing him and exagerrated pain. but still i would like to get and ultra sound
of abdomen if the pain persists , and a stool analysis done . avoid deep fried food, junk foods, give him soft diet
, if the pain is not relieved , he needs a doctor to review him.
