K, this happened twice this year so far.
everything will seem normal, I have some abdominal pain, then all of a sudden I start to feel dizzy and everyone's voice gets quieter and quieter and (once I fainted, the next time I realized I was going to, and sat down), and after I have this feeling I always get diarrhea.
the doctors took blood tests and everything, they think there's nothing wrong with me. Please help. I'm scared this will happen again.
