What is a bruise?
A bruise is an injury of the tissue under the skin that
causes an area of discolored skin. Another word for bruise
is contusion.
How do bruises occur?
Bruises often result from an injury such as a fall or blow.
Small blood vessels bleed into the tissues under the skin
and cause the skin to change colors.
There are things that may make you bruise more easily, such
as medicines or supplements, a lack of certain vitamins, or
a blood-clotting problem. Older adults bruise more easily
because their blood vessels are more fragile and their skin
thins with age.
What are the symptoms?
The usual symptoms are pain, swelling, and discolored skin.
Some bruises may cause only a little tenderness, but deep
bruises of muscles can make it very painful to move. Bruises
are usually purple at first and then slowly fade over a
couple of weeks to various shades of brown, yellow, and
green.
How are they treated?
Most bruises need no special treatment. The body will
repair the bruised area and the skin will return to a normal
color.
Bruises on the abdomen, chest, or lower back after injury
can be a sign of damage to internal organs. Bruising around
both eyes ("raccoon eyes") after injury to the head can also
mean serious injury. Get prompt medical care for these
types of bruises.
How can I take care of myself?
Here are some things you can do to relieve pain and reduce
swelling:
- Rest the part of your body that is hurt, particularly if it is painful.
- Put a cold wet cloth, ice pack, or package of frozen
vegetables wrapped in a cloth on the bruise for 15 to 20
minutes at a time (longer might cause frostbite), 4 to 8
times a day for 1 to 2 days after the injury.
- Lightly wrap the bruised area with an Ace bandage or soft cloth if it is swollen.
- Keep the injured area above the level of the heart.
- When the swelling has stopped, usually after the second
day, put warm washcloths on the injured area to help your
body reabsorb the blood.
- Do not massage the bruised area.
Contact your health care provider if:
- You are getting bruises for no reason.
- A bruise does not heal.
- You have bruising around the eyes.
- You have bruising with unexplained bleeding from the
nose, gums, or eyes.
- You have blood in the urine.
How long do the effects last?
Most bruises go away in a couple weeks. Severe bruises
cause deep tissue damage and may take several weeks to heal.
