About 6 weeks ago I started having severe pain in stomach right under ribs. And I belch and belch sometimes dry heave it is so bad. Break out in clammy sweat. I cannot relate it to any specific food. Last nigh I was craving crunchy and the only thing I could find crunchy in the house was some croutons, I ate maybe 6. 30 minutes later severe pain with the belching and dry heaves.
