First, read the English article below.

No matter how well you take care of your injury, you might still get an infection. If your toe is infected you might see red streaks running up your toe, foot, or leg. You might get a fever of 100.4ºF (38ºC) or higher. Pus – thick, white or colored drainage from the injury – is another sign of infection. See your doctor if any of these signs occur, because infections can be serious. Your doctor will prescribe you antibiotics if an infection is present. Take these as prescribed and until they’re gone. See your doctor if your pain is severe enough to interfere with sleep or daily activities, does not improve 2 hours after taking pain medicine, or gets worse over time. If you have swelling that gets worse or does not improve after medicine, ice, and elevating your foot, get help. Ask questions like, "My toe hurts more today than it did yesterday and Tylenol isn't helping, is that okay?" or "How much swelling is normal?" Sometimes, a crushing injury to a toenail (like having a heavy object dropped on your toenail) can cause a subungual hematoma – bleeding underneath the nail. This creates a little pocket of blood under the nail, which can be uncomfortable because of the pressure. It looks like a dark blue, black, or purple bruise like splotch beneath your nail. If the bruise is less than ¼ the size of the nail, it will probably resolve on its own. Otherwise, see your doctor because you may need to have the fluid drained from under the nail to prevent further pain and injury. Don’t attempt to do this on your own or for someone else. See a doctor. Your doctor will drill a very small hole in your toenail to let the blood drain out. This procedure shouldn’t hurt, and draining the blood will make your toe feel better because it relieves the pressure. Whether your toenail will regrow normally depends on whether or not the nail bed was damaged. If you’re worried about how your nail might look when it grows back, speak to your doctor about the possibility of a small surgery on your nail bed. If you can see visible damage...
