HiI'm 44 this year and Im a female. It's going on two years now that I get this throw up feeling for about 15 to 20 seconds then it goes away. I've had colonoscopy and a catscan and they never got to do the Upper where they go through your throat and look at your stomache, by this time the doctors diagnosed me with IBS after my colonoscopy, and I know this is not my problem. After about 3 months when I was diagnosed, the symptoms went away but then returned shortly there after, and I have it daily now again and have had ever since. At the time when my doctor had test run on me I had, had the flu but my diahrea would not go away so that's why they started to do test. Now I'm regular on bowel movements with no diahrea ever but still have this sickness in my stomache. help! Any advice
