Nosebleeds, also known as epistaxis, is a common occurrence that can happen for any number of reasons. They will typically start without warning and can vary in severity from a slow trickle to a full-out gush. The inside of the nose has a lot of tiny blood vessels right under the surface of the skin that can be easily irritated. Nosebleeds can occur for two of the most common reasons – nose picking and dry air, making them susceptible to bleeding. There are also many other common reasons for nosebleeds such as allergies, sinus infection, aspirin use, chemical irritants, common cold, deviated septum, nasal sprays, trauma, foreign object in the nose, and others. In the majority of cases, nosebleeds aren’t serious and don’t require medical intervention as they will resolve themselves quickly. Nosebleeds can affect anyone, at any given time, although some people may be more likely to get them or get them on a somewhat frequent basis.
