My stomach hurts and don't know why. the only thing that helps is food. but it doesn't really feel like a hunger pain. what could it be?

Possible Ulcer: The first thing that comes to mind with this description is an ulcer. The often get better with food and then may actually get worse a little while after eating. Could be gastritis or even sometimes anxiety can cause these symptoms. Would need to know a little more. You may need some additional tests and possible and endoscopy to answer this thoroughly.
