I've had several testing done, from CT, MRI's, Upper GI and Tilt table test. I've seen doctors from NC
, VA and MD. No one seems to know why I have these episodes of stomach cramps and blackouts. These always occurs during mid-morning hours 3-5am. The pain is so severe it wakes me and I rush to the bath room and blackout. I usually stays out for about a 1 or 2 mins and it appears that I am having epillsey, but I was tested for that and the doctors ruled it out.
