Nosebleeds involve bleeding from the inside of your nose. Many people have occasional nosebleeds, also known as epistaxis (ep-ih-STAK-sis). Nosebleeds may be scary, but generally are a minor annoyance. Frequent nosebleeds are those that occur more than once a week.
Seek emergency medical attention if nosebleeds are severe, last longer than 30 minutes, interfere with breathing or follow an injury.
