Blood or bleeding under the skin due to trauma of any kind; typically black and blue at first, with color changes as the bruise heals.

Ice for 20 minutes several times for a day or two. Rest and keep the bruised area above heart level. For swelling, wrap the area in an elastic bandage, but not too tight. A nonprescription pain reliver may help.

See a healthcare professional at once for:

• Severe pain.
• A lump that forms over the bruise.

Make an appointment to see a healthcare professional if the bruising is:

• Still painful after three days.
• Unexplained or unusual, such as from gums or nose.
• Frequent, large, or painful.
