i am an athletic and healthy teenager. for the past 4 years i have lost conciousness for hours at a time , with no apparent reason.i have gone to the doctor ,done a brain scan but cant find anything wrong.i usually pass out when im standing, like when i was doing rotc inspections, the weather was nice and cool, and there was a bit of sun. i was standing up for about 45 minutes when i felt dizzy and shortness of breath. i went to sit down and i felt that i was shaking. first it started in my arms then it was in my legs. i felt numbness in my arms and legs also. i had tried to get up, but i blacked out and woke up with my AI (army instructor) trying to awaken me.
if anyone knows whats wrong with me , please tell me.
