started with pain 7 hours after eating a heavy meal, like a punch on the stomach and went away after few hours. Had that episode a couple of times with in a month. A month later i had it again but it never completely went away ( has been 8 days) This time accompanied of gastritis, heartburn and a discomfort under my right rib cage close to the top of my stomach, the discomfort increases 20 min after I eat a meal and it feels worst when I am sitting ( there is no pain but there is pressure and is sometimes achy)
