== Bruises ==

'''Bruises''' ({{IPA|ˈbruːz}}), also known as ''contusions'', are a type of [[hematoma]] of tissue in which the capillaries and sometimes venules are damaged by trauma, allowing blood to seep, hemorrhage, or extravasate into the surrounding interstitial tissues. 

=== Etymology ===

The word ''bruise'' comes from the Old English ''brysan'', meaning "to crush, break". 

=== Causes ===

Bruises are usually caused by [[blunt force trauma]] that damages blood vessels beneath the skin, which do not break open as in a laceration. This results in a visible discoloration as blood accumulates just beneath the skin surface. 

=== Symptoms ===

Symptoms of a bruise include pain, swelling, and skin discoloration. The bruise may start out as a reddish color, then become blue or dark purple as it heals. 

=== Treatment ===

Treatment for bruises often involves rest, ice, compression, and elevation (RICE). Over-the-counter pain medications may also be used to help manage pain and inflammation. 

=== Related Terms ===

* [[Petechiae]]: Tiny, circular, non-raised patches that appear on the skin or in a mucous or serous membrane.
