What to Know About Bruises

How we reviewed this article: · Healthline

It is common to get occasional bruises from minor injuries. However, you can also develop bruises from more serious health conditions, including varicose veins and leukemia.

Black and blue marks are often associated with bruises, although the appearance can differ based on your skin tone. A bruise, or contusion, appears on the skin due to trauma. Examples of trauma are a cut or a blow to an area of the body. The injury causes tiny blood vessels called capillaries to burst. Blood gets trapped below the skin’s surface, which causes a bruise.

Bruises can occur at any age. Some bruises appear with very little pain, and you might not notice them. While bruises are common, it’s important to know your treatment options and whether your condition warrants emergency medical attention.

There are

three types

of bruises based on their location on your body:

subcutaneous, bruises occur just beneath the skin

intramuscular, bruises occur in the underlying muscles

periosteal, bruises occur on the bones

Symptoms of a bruise differ depending on the cause.

Discoloration of the skin

is often the first sign. Bruises can vary in appearance depending on your skin tone.

on dark skin tones, bruises

may appear

brown, purple, or darker than the surrounding skin

on medium skin tones, bruises may appear red or yellow

on light skin tones, bruises may appear red or purple

It is important to remember that bruises change color throughout the healing stage. On dark skin tones, they may at first be difficult to make out.

Most bruises heal on their own. You can typically treat associated symptoms, such as pain and swelling, at home with some of the following options:

Use an

ice pack

to reduce swelling. Wrap the pack in cloth to avoid putting it directly on your bruised skin. Leave the ice on your bruise for 15 minutes. Repeat this every hour as needed.

Rest the bruised area.

If practical, raise the bruised area above your heart to keep blood from settling into the bruised tissue.

Take an over-the-counter medication, such as acetaminophen (Tylenol), to reduce pain in the area.

Some people may bruise more easily. This includes:

Older adults: Bruises tend to be

more common

in older adults. As you age, your skin becomes thinner, and the capillaries under your skin become more prone to breaking.

Women: Women can be

more prone

to bruising as their skin typically has less fat and collagen, and more estrogen.

You may also notice bruising after receiving an injection or wearing tight clothing.

In most cases, easy bruising is nothing to be alarmed about. However, if this is a recent development, you should talk with a healthcare professional about potential causes and treatment options.

Bruises that develop after a

cut

,

burn

, fall, or injury are normal. It’s not uncommon to develop a knot in the area of bruising. These bruises form as part of your body’s natural healing process. In most cases, they’re nothing to worry about.

However, some symptoms can indicate a more severe condition. You should seek medical attention if you have:

increased bruising while taking aspirin (Bayer) or other

blood thinners

swelling

and pain in the area of bruising

bruising that occurs after a hard blow or fall

bruising that occurs along with a suspected

broken bone

bruising for no reason

bruising accompanied by bleeding from your

gums

,

nose

, or mouth

bruising accompanied by blood in your

urine

,

stool

, or

eyes

a wound that bruises,

reopens

, and produces pus, clear liquid, or blood

If a child has unexplained bruising, you should speak with a healthcare professional to determine the cause. Unexplained bruising on a child can be a sign of serious illness or even

abuse

.

It is common to get occasional bruises from minor injuries, such as accidentally bumping a body part on a doorframe. However, you can also develop bruises from more serious health conditions, including varicose veins and leukemia.

If you have bruising that occurs repeatedly or for no reason or burning that has not gone away after months, it is important to speak with a healthcare professional. It may be the result of an underlying health condition that needs to be treated promptly.
