Caused by bleeding into the skin or into tissues beneath the skin, a bruise can develop rapidly or emerge a few days after an injury. Bruising can also indicate a deep injury. Elderly people and those taking anticoagulant (anti-clotting) drugs can bruise easily.

Your aim in treating bruising is to reduce blood flow to the injury, and thus minimize swelling.

1. Raise and support the injured part in a comfortable position for the casualty. 
2. Place a cold compress over the bruise for at least ten minutes.
