Definition

A contusion is when blood vessels are damaged or broken after an injury. Blood and fluid then leak from the injured blood vessels into the tissue. This results in a discolored, purplish area in the skin. It takes 2 to 3 weeks to go away. A contusion is also called a bruise.

Causes

Contusions are usually caused by bumps to the skin. This may happen from falling, bumping into something, or being hit, or kicked.

Risk Factors

Almost everyone gets contusions. Those with a higher risk are:

  • Children and teens
  • People who play contact sports
  • People with blood-clotting problems
  • People taking blood-thinners, such as aspirin

Symptoms

Contusions may cause:

  • Skin discoloration—usually blue and/or purple, fading to yellow
  • Pain
  • Swelling

Diagnosis

Contusions are diagnosed by physical exam of the skin.

Treatment

The goal is to reduce swelling and pain by:

  • Applying ice or a cold pack to the injured area
  • Elevating the injured area above the level of the heart
  • Taking pain medicine, as advised by the doctor

Prevention

Using proper safety equipment can help prevent contusions.
