When the foot is broken and the back of the foot is swollen, the following methods can be used for treatment: 1, braking and resting: can reduce bleeding and swelling and avoid aggravation of local injury. 2, cold compress treatment: immediately after the injury, apply cold compress to the local area, use a towel wrapped in an ice water mixture and apply a continuous cold compress to the local area, which can cause vasoconstriction, reduce exudation, limit the scope of traumatic inflammatory reaction and relieve pain and swelling. 3, local compression bandage: if the swelling is not serious, it is suitable for compression bandage to limit the progress of swelling.
