A typical bruise is a contusion caused by traces of blood
escaping from small vessels that lie close to the skin's
surface. Since our blood vessels become more fragile with age,
the elderly tend to bruise easier than healthy adults and
children. Conversely, if a child sustains excessive bruising, it
may be an indication of a more serious injury and should be
treated accordingly. If the bruise is on the victim's head, he
may've have sustained a concussion and should be checked for
head trauma. To reduce the bump and minimize the pain, have the
victim elevate the injured area and apply a commercial ice pack
or ice cubes wrapped in a towel for 30 to 45 minutes. Depending
on the extent of the injury, this process should be repeated for
a few days or until the swelling and the pain begin to
dissipate.
