I am just trying to research possible causes of my feeling nauseated immediately after eating, to include feeling light-headed, fatigued (like somebody just sucked the blood or air out of me). I have to stagger in and prop myself up in my bed until the discomfort becomes bearable. Lately, my chest aches, It was pressure more behind the left rib cage, I have been told that my kidney stone xrays show a gallstone and I have a hernia,
