So we can see a bruise on the intact skin. Depending on where the congestion occurs, it affects the body in different ways. For example, when the blood stasis is on the limbs or trunk of the human body, the damage to the human body is relatively small. The human head is often touched in production and life, causing congestion to occur on the human head. When the amount of congestion on the human head is too large, it may compress the nerves of the injured person's head and seriously affect the injury. the body function of the patient.
