Dear Dawn, I think there is no need to worry. The most important thing is that doctors ruled out surgical emergency...
There are no abnormal findings,both diagnostic and laboratory. However, if symptoms occur again it shouldnt be underestimated.
in this age is usually caused by: Infections, Food-related, poisoning
and surgical problems. The best diagnostic test now is "time". Just be patient, listen and watch your child and his complains. look for any sign of pain and change in his behavior. If you notice fever, diarrhea
, weight loss
, urine and stool color change you should go to hospital. If symtoms persists, best way for evaluation is abdominal and pelvic CT scan(despite its disadvantages) but dont hurry...
Wish you good health, Dr. Ivan Romic (Rominho)
