Causes of Nose Bleeding most commonly are, trauma to the nose. Trauma to the outside of the nose, such as a blow to the face, or trauma inside the nose, such as nose picking or repeated irritation from a cold, can cause a nosebleed.
Less commonly, an underlying disease process, such as an inability of the blood to clot, may contribute to the bleeding. Abnormal blood vessels or cancers in the nose are rare causes of nosebleeds. High blood pressure may also contribute to bleeding but is almost never the only reason for a nosebleed.
