A contusion is a fancy word for a bruise. Contusions are a type of soft tissue injury and are often caused as a result of sudden or prolonged impact to your body. This damage done to the soft tissues in your body causes blood to gather around the affected area, near the skin, giving the appearance of a blueish-reddish bruise. While most contusions heal themselves over a period of time, if you’ve been injured it’s always best to check with your physician about any injury complaints that you may have.
