Reoccuring nasuea and vomiting at random times.
Until now, I have always been very healthy. I am 16 and I would say physically fit. However, over the summer, I have attended a large convention and a rennaissance fair and gotten ill at both. I had no appatite and was hit with a sudden wave of nasuea, fatigue, weakness, and projectile vomiting. I couldn't even walk without collapsing. I doubt it is contagious because none of my friends that were with me were sick at all. I didn't eat anything unusual. Both of these places had cigarette smoke and my mom has a known allergy to this. Has anyone heard of this kind of allergic reaction? I also have a sharp pain under my ribs on the left side, but I don't know ithat is relevant. Can anyone help me or suggest what I could look into?
