A nosebleed happens when one of the blood vessels in the lining of the nose bursts. Nosebleeds may be caused by infection, injury, allergic reaction, nose picking or an object being pushed into the nostril. Another name for nosebleed is epistaxis. Bleeding from the nose is common in children and is usually not serious. Seek medical attention if nosebleeds are severe, frequent or prolonged.
There are many different things which can cause a bloody nose or blood-streaked nasal mucous. In a child, a pediatrician is the best physician to make an initial assessment and determine whether other physicians such as ear, nose, and throat (ENT) doctors should become involved. The skin lining the nasal passages is very thin and delicate which is what makes it prone to bleeding with even minor irritation. Irritating factors can include cold/dry weather; seasonal or environmental allergies; or an infection that causes typical upper respiratory 'cold' symptoms. Some other common causes of bleeding from the nose include trauma or a foreign body (in a child, most often related to nose-picking).
