A bruise, or contusion, is a type of hematoma of tissue in which capillaries and sometimes venules are damaged by trauma, allowing blood to seep, hemorrhage, or extravasate into the surrounding interstitial tissues.
Contusion is really just a fancy word for a bad bruise. Professional athletes are often benched suffering from contusions. After all, if they're being paid millions, it sounds kinda wimpy to pull them because they're suffering from a...bruise. A contusion is any damage to the body that doesn't break the skin but ruptures the blood capillaries beneath, resulting in a handsome-looking discoloration. For once, it's a medical term not used widely to describe a broader emotional or psychological state.
