...time i eat..that lasts hours? for the past 2 weeks, its gotten worse each day and when I eat, about 20 minutes after I get a terrible burning and pain in my stomach right above my belly button. it gets so severe that I get hot flashes, feel like I am going to throw up sometimes, and its just unbearable. the pain lasts about 4 hours, sometimes all day/night but a little less severe.
