When a sprain occurs, the patient will injure the local muscles and other soft tissues, as well as the local capillaries, which will cause the blood vessels to bleed and produce bruising. The patient may experience local pain, swelling, and subcutaneous bruising. After a sprain with bruising, the patient can be given local braking, while the injured part can be applied externally to activate blood circulation and eliminate blood stasis, reduce swelling, relieve pain, and promote the absorption of bruising, reduce swelling, and also relieve pain. The patient can also be instructed to take oral blood-activating drugs, such as oral bruising pills and bone wound spirit, which can effectively promote the absorption of bruising. Patients should not dispose of this condition on their own, such as blindly massaging and rubbing, which can aggravate the symptoms of subcutaneous bruising.
