A nosebleed happens when one of the blood vessels in the lining of the nose bursts. Nosebleeds may be caused by infection, injury, allergic reaction, nose picking or an object being pushed into the nostril. Another name for nosebleed is epistaxis. Bleeding from the nose is common in children and is usually not serious. Seek medical attention if nosebleeds are severe, frequent or prolonged.
Abnormal blood clotting: Anything that interferes with blood clotting can lead to nosebleeds. Medications, even common ones like aspirin, can alter the blood-clotting mechanism just enough to cause bleeding. Blood diseases, such as hemophilia, also can provoke nosebleeds.
