(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.
