I have had severe stomach pain in my diaphragm area and i have been throwing up stomach bile for 2 years now. The dr says it is ulcers and has put me on prevacid that is not working i have had 2 cat scans they all come back normal. i believe it is my gall bladder i get bloated and berping releases a little of the discomfort but not all. i also get bad gas cramps and cannot release the gas. i get a really horrible pain in my stomach at the top, almost like a bad hunger pain, then i throw up stomach acid and i have pain after this for a couple days then it goes away then it will come back. this has been going on for years and i want answers. please help me
