When you say he has a burning in one spot in his stomach, one thing comes to mind with me is maybe Peptic Ulcer Disease. If he has an Ulcer then he would have that burning in one spot. It dosn't always show up in test. My experience with test being done, I have seen more negative then positive when they should be just the opposite.

The food would calm down the burning and if his stomach is full at night then he wouldn't have the burning. I take prevacid for my GERD and PUD. I can stay off of it for a few days and my stomach and esophogus is a mess. I had so many test when I first started with my illnesses and nothing showed anything until it was worse. I have had test that show one thing and then when they go back it shows nothing and visa versa.

This is just a thought on the PUD. If he has an ulcer or the starting of one then he would have the burning.

I hope he doesn't have the RSD. I hate to see kids go through what Ali and others on here have went through.

Good luck to you and your son on getting the answers soon.
