Since I was about 10 years old I have been having these
fainting spells. I never have them sitting down just when I am standing. I feel a pressure in my head, then my vision goes black, I hear a roaring in my ears, and they last for only seconds. When I come back I am slightly confused for a second then my head hurts a little, my heart is pounding, I sometimes have coldsweats, and my breathing is faster. I am 24 years old and in the last couple years they have been getting a little worse.
