If the swelling of the foot is caused by simple soft tissue injury, you can apply red medicine aerosol or white medicine aerosol, which can be used topically to reduce the temperature and swelling. It can also be combined with local compression bandages, which are applied from the distal end of the toes to the proximal end of the lower extremity, to relieve swelling. If the fracture is complicated, external fixation in plaster is also required. In patients with swollen feet caused by venous thrombosis, anticoagulation therapy should be actively administered to significantly relieve swelling, either with rivaroxaban tablets or with low molecular heparin calcium, which should be injected subcutaneously.
