Repeated nosebleeds may be a symptom of another disease such as high blood pressure, allergies,a bleeding disorder or a tumor of the nose or sinuses.
Nosebleeds usually involve one nostril, but occasionally both nostrils are involved. If one nostril becomes partially blocked with a blood clot, the blood might flow out the other nostril or down the back of the throat. In a posterior nosebleed (higher up in the nose), large amounts of blood typically flow down the back of the throat. The amount of bleeding from a nosebleed can vary with posterior bleeds usually bleeding significantly more.
