Foot injuries usually require elevation of the affected limb with the ankle higher than the knee joint and the knee higher than the hip joint. The purpose of elevation is to promote venous blood return to the distal limb, as local soft tissue contusions after trauma can affect blood circulation to the distal limb and increase swelling. There will be obvious pain, and even easy to secondary to the formation of lower limb venous thrombosis, the best physical therapy is limb elevation, while in the acute phase of the injury, you can choose the method of local ice, ice wrapped in a towel and applied to the injured part, local swelling and pain relief effect. During the treatment period, attention should be paid to rest, not to strain, and appropriate activities or muscle contraction exercises can promote venous blood flow back. If thrombosis occurs, anticoagulation therapy should be actively chosen, because the embolus dislodged easily complicates the occurrence of pulmonary embolism.
