What is a nosebleed?
A nosebleed (also known as epistaxis) is bleeding from the nose due to burst blood vessels at the front or back of the nostrils. Your nose is full of tiny, delicate blood vessels that can be easily damaged and as a result bleed. If you’ve suffered a head injury or have had recent surgery on your nose, or your arteries start to harden (atherosclerosis) bleeding can come from deeper in the nose.
