Why is my ankle black and blue?

If your ankle is black and blue, it is a sign that damage has occurred to the soft tissues (i.e., muscle, tendon, skin, fat) in your ankle. The black and blue appearance of your ankle occurs because tiny blood vessels within the soft tissues (called capillaries) have been torn. When these tiny vessels are damaged, blood is allowed to escape the vessels and leak into the tissue. This black and blue appearance (a.k.a., bruising) can linger for several days, but will usually go away on its own. The bruising may change colors over several days because of chemical processes that are happening in the area. There is no need for concern regarding the changing color of a bruise.
