If there is a contusion on the surface of the skin, you should do a good job of disinfecting with iodophor. Secondly, if the swelling and pain are obvious and even the range of motion of the toe is restricted, you should go to the hospital for a radiograph to rule out the possibility of a fracture. If there is no fracture, bed rest for 3-4 weeks, the above problems can be gradually recovered; if the fracture is relatively light, external fixation in plaster should be performed for 1-1.5 months for protection.
