Most nosebleeds start from the many small blood vessels that lie in the front part of your nose,
and are fairly easy to stop yourself.
Nosebleeds that start in back part of your nose come from bigger vessels, and tend to be heavier, and harder to stop.
Here's what to do when you have a nosebleed:Sit down and firmly pinch your nose just above your nostrils, where your nose is soft. Breathe through your mouth.Keep pinching for about 10 minutes to 15 minutes, without releasing the pressure.
