What causes nosebleeds, and can they be avoided?
Nosebleeds are usually the result of broken blood vessels in the front of the nose. Direct injury, dry weather, frequent nose-blowing, allergies, cocaine use, and nose-picking are common causes. A cotton swab coated with antibiotic ointment will lubricate the outer nasal passages and lessen the effects of dry weather. Occasionally, recurrent nosebleeds may be a sign of an underlying problem like high blood pressure. Seek medical attention for any recurrent nosebleed or one whose cause is not readily apparent.
