If a sudden blow to the body would occur there would be bruising and potentially broken bones. If the blow is hard enough maybe a concussion. Depending on where the blow to the body is located there could be sprains and or blood.
A sudden blow to the body can cause a third degree sprain (III sprain), depending on the degree of intensity that the blow was established.
In a third degree sprain it can cause a complete rupture of a ligament, cause severe pain, cause endemic, swelling, tenderness and can cause a serious injury.
