Health Tip: When Bruising is a Red Flag

(HealthDay News) -- Bruises occur when blood vessels below the skin rupture, says Cleveland Clinic. Most bruising is caused by minor accidents, medications and age. Bruises caused by minor injuries usually disappear within a week or two.

Cleveland Clinic suggests getting a bruise checked by your doctor if it:

• Shows no signs of improvement after a week.
• Is located on a part of your body where injury or accident is unlikely.
• Keeps occurring or comes back.
• Involves unusually large, unprovoked bruising.
