Question

Answer 1

The symptoms may not have been from a loss of blood. It could have been slight shock from just the sight of blood and the pain of being cut. Even a drop of blood could make you feel light headed and weak.

But you say you couldn't get it to stop bleeding? You may want to find out if you have hemophilia. It's a condition where your blood doesn't clot normally.It's definately something to be aware of.

Although, if you had been drinking at the time your blood may have just been thinned by the alcohol.

Good luck.

Answer 2

http://en.wikipedia.org/wiki/Blood_loss

The circulating blood volume is approximately 70 ml / kg of ideal body weight. Thus the average 70 kg male has approximately 5000 ml of circulating blood. Loss of 10-15% of total blood volume can be endured without clinical sequelae in a healthy person.

Answer 3

you probably need stitches-get to an ER and don't drive you may pass out---replenish the fluids you lost- drink water.
