To make this short - I've had those "near-fainting" spells since I was about 13.
I know this is normal for girls and it happens once in a while.
However,
Over this summer I've had these "near-fainting" spells nearly everyday for about 3-4 months and completely fainted twice. It's usually when I get up (as expected) and I can't move as everything slowly closes in.
Background info - I'm 19 (female), I run track for the University and eat healthy.
I'm not looking for a complete diagnosis but has anyone experienced this and have any idea what it could be related to?
