Thank you for your query on Healthcare Magic.
Which part of abdomen he is getting pain?
The last episode of his stomach pain may be due to the gastroenteritis
But I advise you to go for basic evaluation with ultrasound
abdomen, CUE, stool routine examination after the physical examination of the child by a Pediatrician
If any significant problem is there, the investigations will detect.
If these investigations are normal, nothing to worry as the pain may be due to functional pain.
Therefore I advise you to first consult your Pediatrician for the physical examination of the child and go for basic investigations after his advise.
Hope I have answered your query.
