I agree with the CT scan, which can exclude a blockage or colitis.
If negative, as it appears to be the case, the next steps to consider would be to send the stool off for culture and analysis, as well as an evaluation for malabsorption.
I would also consider a colonoscopy, which can comprehensively look at the lower bowel, as well as blood tests to look for celiac disease.
These options can be discussed with your personal physician, or in conjunction with a pediatric gastroenterologist.

Thank you. The pediatric gastroenterologist has ordered all the tests you mentioned.
Is it possible that this could be a virus? The reason I ask is that the symptoms seem to have disappeared as quickly as they started. Yesterday afternoon he ate, had no pain or cramping the again last night- ate with no pain or cramping afterward.
The symptoms started one week ago and seem to have now stopped abruptly.
