If your foot is swollen, check the injured area for skin damage. If there is skin damage, first disinfect it with iodophor and then apply a sterile dressing. If there is no skin damage, apply cold compress within 24 hours, which can make the local capillaries shrink and reduce the local hematoma, thus reducing the pain. 24 hours later, change to hot compress, which can accelerate blood circulation and promote the absorption of the hematoma, thus reducing the pain symptoms. After recuperation, if the local pain does not improve but continues to worsen, it is necessary to go to the hospital to further improve the examination to see if there is a fracture. If the fracture is simple, external plaster fixation should be performed, and oral medication to promote blood circulation and improve circulation should be taken to facilitate fracture recovery. If the fracture is dislocated, surgery should be considered, with incision and internal fixation, and external fixation after surgery, which requires a longer recuperation time. After surgery, you should also pay attention to rest, pay attention to local protection, avoid prolonged walking and standing, and eat nutritious food and avoid spicy and stimulating food.
