A bruise (also called a contusion) happens when small blood vessels under the skin leak blood after an injury. The trapped blood might show as red or purple marks on the skin or, if the bruise is very deep and involves the muscle, nothing may be visible on the skin. A bruise usually hurts when touched, especially for the first few days after the injury.

As bruises heal, they may turn different colors as they fade away. Most are gone after 2 weeks.

For 2–3 days, to help with pain and swelling:

• If your health care provider says it's OK, give your child medicines like acetaminophen (Tylenol^® or a store brand) or ibuprofen (Advil^®, Motrin^®, or a store brand) as needed for pain. Follow the directions on the label for how much to give and how often.
• Place ice wrapped in a towel on the bruise for about 20 minutes several times a day. Do not put ice directly on the skin.
• Wrap the toe or foot in an elastic bandage. It should be tight enough to give support but loose enough that you can easily put a finger under it.
• Keep the toe above heart level by resting it on a pillow.

Follow your health care provider's advice for:

• Any exercises or stretches your child should do and any activities to avoid.
• If you should try a heating pad (usually about 2 days after the injury).
• When your child should follow up.

• The pain or swelling gets worse.
• Within 2 weeks:
  • The bruise and pain haven't gone away.
  • Your child isn't walking normally.
  • Your child seems to have a lot of bruises or gets bruises for no clear reason.

Your child:

• can't move the toe
• has tingling or loses feeling in the toe

How do health care providers diagnose a toe bruise? Health care providers carefully examine the injured area and ask about what happened. Usually no testing is needed, but sometimes they order an X-ray to make sure there are no other injuries.

How do bruises heal? Bruises usually go away in 2 weeks. While it heals, the bruise changes color as the body breaks down the blood:

• At first, a bruise looks red or pink because of the trapped blood under the skin.
• Within 1–2 days, the bruise will look bluish-purple or sometimes black.
• After 5–10 days, the bruise looks green or yellow.
• After 10–14 days, the bruise may turn yellow-brown or light brown.

What can help prevent toe bruises? Most kids will get bruises from time to time. But it can help to:

• Wear shoes when doing sports or other activities.
• Wear shoes that fit well.
• Use proper technique during sports and practices.
• Pay attention to things that are on the floor or ground.
• Keep floors clear of clutter to prevent tripping and stubbed toes.
