I hit my nose and it won't stop bleeding. what can i do?

Pinch nose,use Afrin (oxymetazoline): Nosebleeds occur for a variety of reasons. In children, 90% of nose bleeds occur in the front near the nostrils, which is why pinching the nose helps stop it, since pressure is applied. In adults, it can also be posteriorly as well, so pinching helps in fewer cases. Lean head forward, not backward, so you do not swallow the blood. Spray afrin (oxymetazoline). See your doctor/ent to look in nose and discuss causes.
