Hi. My son who is almost three has been complaining of belly button and bum pain for sometime. He has been to the doctor they can t find anything wrong. His diet is not that great. He is a very picky eater. He does like chocolate chip muffins though. Lol. I called the doc again on Monday about the bum pain. Waiting for a reply. I am just scared because your mind starts thinking of other things like cancer. Any thoughts would be appreciated. I feel like he complains right after he eats or drinks something.
Hi, I have gone through the medical history of your grandson and understood his concerns. From what you are describing, the complaints right after he eats or Chat Doctor.  I advise scheduling an appointment with gastroenterologist pediatrician for further evaluations. All the best!
