i have pretty severe acid reflux; not sure if any of you physically have experienced it in such a stressful way as i have, but it has been going on for a few years now; off and on. i generally take a zantec before i eat, etc. it gets unbearable sometimes. also, for a week my stomach has been severely crampy/tight. the tightening feeling of small off and on sharp pains have been throughout my whole abdomen that i cannot tell where it is coming from. could be an ulcer or a few other problems but it would occur around navel, sides and above....also have been nauseous all week. could be a number of things, not being able to eat til late after a long day, but i get nauseous within a few after ingesting food. what do you think i could be suffering with?
