The child is four years old, and his left ring finger is caught in the door. At first, all nails were purple. After a day, they will fade and turn white, and then the nails will start to fall off.

Hello, this is not a big problem. The nail roots of the baby's nails are not affected, but what needs to be done now is to take anti-inflammatory drugs orally to prevent infection, and at the same time, it needs to be disinfected every day. If the symptoms get worse, it is best to go to the hospital to pull out the nails, let them heal naturally, and then grow new nails.
