OK, I've been freaking out the last week because there is a sv* going around my town. A while ago, I felt hungry, but also had some gurgly feelings in my stomach. I ate a little bit, and then felt the need to have diarrhea. Actually, it was mainly gas. I guess I'm just scared it may be a bug. Is there usually a lot of gas with a sv*? Does it sound more like IBS?
