Bruises are small torn blood vessels under the skin, most often
caused by a bump or a fall. Blood seeps into tissues, causing the
black-and-blue color. Most bruises go away within 2 to 4 weeks. Home treatment
is usually all that is needed.
Bruising or discoloration can be more serious when it develops within
30 minutes of the injury. This can occur with a severe bruise or a broken bone
in the nose or other face, such as a broken cheekbone. Bruising behind an ear
is called "Battle's sign." Bruising around both eyes is called raccoon eyes.
Bruising in these areas that is not caused by a direct injury may be a symptom
of a skull fracture.
Nose or facial injuries are more serious whey they occur in people
who have conditions or take medications that interfere with blood clotting.
Bruising may be more severe or cover a larger area. There is an increased
chance of bleeding in injured joints or bones.
Your health professional can evaluate your bruising and discoloration
and treat any underlying cause.
