I'm glad you've been to the doctor. I don't know what to think about your symptoms, but I hope they will continue to run other tests. Did they run any blood work when you went into urgent care? Did the diarrhea come first, or the heart racing/blacking out feeling come first?

I did wonder about whether you may have just been ill... some sort of food poisining or a virus. However, if this is repeating itself over and over, then I'd be looking for another cause. I don't think you'd be getting the same germ over and over again....that seems like one of those answers we invent to have an answer.

Blood sugar and potassium level are two things I'd wonder about, but I bet there are many others I'm not aware of. If they didn't run blood work, I hope they will if it happens again.

I hope you are feeling better~
