I am only 20 years old and the doctors diagnosed me with IBS about a year ago. Lately it seemed to get worse. Most of the time I don't even think I have it. Sometimes I have diaherra other times I vomit and sometimes I do both but most of the time my stomach just hurts really bad and I feel like I'm going to throw up but I never do. I always feel like there is something hot going through my veins and it really freaks me out. Everytime I eat I feel like I'm going to throw up or have D so I don't eat a lot. This happens every couple weeks and lasts for about 2-3 days. I don't know what to do anymore and I'm not sure if I have IBS or something more serious. Can anyone give me advice?thanks
