Nosebleeds
Posterior nosebleed
Bleeding from blood vessels in the back part of the nose (posterior nosebleed), although uncommon, is more dangerous and difficult to treat. Posterior nosebleeds usually involve larger blood vessels than anterior nosebleeds. Because these vessels are in the back of the nose, they are hard for doctors to reach for treatment. Posterior nosebleeds tend to occur in people who Have atherosclerosis (which reduces or blocks blood flow in arteries) Have bleeding disorders Are taking medications that interfere with blood clotting Have had nasal or sinus surgery
