Acute injury

Acute injury is defined by the early onset and short duration of the particular signs and symptoms following the trauma. The injury could involve any one or more of the bodies' tissues.

Typically, the athlete is aware of how the injury occurred, and with an acute sporting injury the common signs and symptoms can include immediate pain, tenderness, swelling, contour deformity or bleeding.

An injury is normally described as being acute until the initial signs of inflammation have reduced, and the healing process has begun, which is normally after 0-72 hours.
