Swelling and bruising in a certain area of the patient’s body is mainly caused by trauma or surgery. The swelling and bruising are caused by the rupture of capillaries under the skin. To quickly eliminate swelling and bruising, the affected limb must be elevated in time to reduce the activity of the affected limb, and then a cold compress should be applied locally within 24 hours after the injury or surgery, 3-5 times for 15 minutes each time, which can effectively reduce capillary bleeding and improve the swelling and bruising. Then, 24-48 hours after the injury, hot compresses are applied locally to promote local blood circulation, thus accelerating the reduction of swelling and bruising. If necessary, it is recommended to go to the hospital for an injection of sodium heptaerythrospermum to eliminate the swelling and bruising.
