what causes bleeding noses
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.
The nose is a part of the body rich in blood vessels (vascular) and is located in a vulnerable position protruding on the face. As a result, trauma to the face can cause nasal injury and bleeding. The bleeding may be profuse, or simply a minor complication.
