From One Mom To Another: I also suffered with stomach pain, especially during my high school years. At 16 I went in the hospital for tests, but they found nothing. (my stomach aches would hit me about the time I got to school which was about the time my cereal milk would hit my stomach - Dairy products are the enemy. I suffered for many years. I told many doctors of my problem with no help. Finally, my stomach pain took me to the ER. I was finally diagnosed with gallstones (at age 41). Your son may not have this but you might ask for a diet for this from your Doc and see if it's any help. No one should have to suffer for years. Alternative methods might be good: hypnosis, relaxation therapy, etc. Also, has anyone suggesed food allergy testing? It's worth a try. Hope this might be of some help.
