Scars and damage from previous nosebleeds that reopen and bleed. Damage to the nasal membrane with repeated use of cocaine. High blood pressure.

Blood can flow from one or both nostrils and can flow into the throat.
Symptoms of posterior nosebleed include bleeding that stops and starts, rapid bleeding from the back of the nose, or a slow, steady ooze. Sometimes the blood flows back into your throat. Especially with posterior nose bleeding, you can lose blood quickly. If you go to your health care provider with a nosebleed, he or she will have you sit up and lean forward to determine the rate and site of the bleeding. Your provider may check your pulse and blood pressure and take a blood sample to check for anemia and your blood type in case you need a transfusion.
