What are the causes and symptoms of nosebleed?
Nosebleeds may result from a number of different causes: • local infections (colds, sinus infections) • systemic infections (scarlet fever, typhoid fever, malaria) • drying of the membranes lining the nose, often during heating season in colder climates • medications, most commonly overuse of nasal decongestant sprays • trauma (from foreign objects in the nose; scratching or picking with the fingers; or blunt trauma to the face) • tumors in the nasopharynx or paranasal sinuses • cocaine abuse • bleeding disorders (leukemia, liver disease, hemophilia and other hereditary clotting disorders) Source: The Gale Group.
