I have had pretty much those same symptoms for over a year now and no doctor has been able to tell me what's wrong with me. I am in pain every day and I was vomitting on a regular cycle of every four-five weeks. I take 2 omeprazole tablets and 2 pepto bismol tablets every day. It helps me from getting sick so often but it doesn't really do too much for the pain. I have even changed my diet and am very careful about what I eat. I can't afford to go back to the hospital, but I know I need GI tests done. If you haven't had those done yet, maybe that's your best bet at finding out what's wrong.View Thread
