Nosebleeds, also known as epistaxis, can be messy and even scary, but often look worse than they are. Many can be treated at home, but some do require medical care. When medical attention is needed, it is usually because of either the recurrent or severe nature of the problem.

Internal bleeding occurs when the inner blood vessels get damaged. The blood then effectively leaks inside of the body, filling up inner cavities, organs and tissues. Blunt trauma classically causes internal bleeding, which often occurs through 'seat belt trauma' or blows to the abdomen.
