You are welcome. You have given a very full history. I am not convinced that your son needs to be on laxatives. He may just have had some stool in his rectum when the Xrays were taken. There is nothing to suggest that he suffers from constipation. While it is possible that his abdominal pain has a psychological cause which is the commonest cause of recurrent abdominal pain in this age group, the story you give does not fit this diagnosis. His problem seems to be more likely to be due to either a condition called 'periodic vomiting syndrome' or possibly 'abdominal migraine'. Read up about both conditions on Google and see if the descriptions fit your son's condition. Putting him on a migraine diet [also available on Google] may help a lot. If his complaint persists it would be best to see your paediatrician.
