WHAT JUST HAPPEND? I Fell Over and...?

Okay what just happened? I really want to know.

I was on the computer for about two hours strait without getting up then I stood up and a couple seconds later my vision went away and got all blury and my feet & hands got all numb and I fell onto the kitchen counter and couldn't get up for like 15 seconds.
Finally I got up and my vision was back to normal and I stood up.

What happened?

Im usually on the computer for longer times and this never happens

I'd say you got a head rush. Happens if you get up too fast without moving for a long time. Your blood pressure could be low too, or you're not getting enough vitamins, exercise, your blood count is low, etc. If it happens again you should probably see your doctor.
That started happening to me when I went vegetarian because I wasn't getting enough b-12 and iron, and wasn't producing enough red blood cells. Now I take vitamin pills and it hardly ever happens.
