hi, im 21 and when i read your story about having blackouts, i have a very similar story.I have severe headachs on one side of my head, I feel like fainting if i stand up to quikly or even when im walking(i have fainted before 3 times in a row). I went to my doctor and she diagnosed me(dont remember the first word), it was _____ movement syndrome. Which she reccomended me to a specialist for my ears. i went and haveto go see some other specialist for the ears,either that there is somethign blocking the blood flow to go quicker or somethign to do with my inner ear.My doctor discribed it has water pipes. The blood doesnt flow and quick as it should to the brain.you need to see another doctor ask for and MRI and a refferal to see an ear specialist.you need to get up very slowly.hope it helps.
