What is a contusion?
A contusion is bruising from a direct blow to a part of the body without breaking the surface of the skin. It is a crush injury to the muscle fibres, in which blood vessels break and there is bleeding and swelling present. The colour of the bruising will be red, black and blue and there will be swelling present.
What causes a contusion?
A contusion is caused by a direct blow to the muscle. This can occur during contact sports, a motor vehicle accident, or a fall.
How serious is your contusion?
In a MODERATE contusion, there is crushing of several or many fibres of the muscle, along with bleeding and swelling. You may experience pain and muscle weakness upon activity.
In a SEVERE contusion, there is crushing of many of the muscle fibres and rapid bleeding will occur under the surface of the skin along with swelling. You will not be able to continue the activity due to a significant amount of pain and muscle weakness.
