Epistaxis, or a nosebleed, is generally caused by a broken blood vessel in the nose or sinuses. Bleeding from the nose, especially when blowing it, is very common and usually not a cause for concern.
An estimated 60 percent of people experience nosebleeds but only around 6 percent of cases require medical attention.
