When to Worry About a Nosebleed

2) Foreign bodies

This is most commonly seen in children, but even adults can do strange things such as sticking small objects in their noses. If the foreign body gets back enough, then it hides within the turbinates and cannot be retrieved by the individual. The foreign body irritates the mucous covering in a chronic fashion and bleeding occurs in episodes. Infection can also occur on top of it causing bleeding.
