Subcutaneous hemorrhage is a condition that occurs when the capillaries under the skin rupture, causing blood to leak out of the blood vessels, mostly due to trauma and compression. Depending on the amount of bleeding, subcutaneous bleeding can be manifested as spots, plaques or hematomas. If the subcutaneous bleeding is short, cold towels can be applied locally to control the bleeding, and then hot compresses can be applied after 48-72 hours to promote the absorption and dissipation of the local blood accumulation. If a large amount of subcutaneous blood accumulation forms a hematoma, local puncture can be performed to drain the accumulated blood, and local pressure bandages can be applied to prevent and control infection after surgery. During the treatment of subcutaneous hemorrhage, it is important to take more rest and avoid strenuous exercise to avoid accelerating blood circulation and causing rebleeding. At the same time, do not eat spicy and stimulating food to avoid local wound infection.
