Question 1: The smashed nails grow thick and yellow. If I only thicken my nails, it must be onychomycosis, and many of them are caused by trauma. Onychomycosis is more contagious and should be paid attention to.

Question 2: What should I do if my nails become like this after being smashed? If there is no bleeding, take care of the injured nail, don't touch it, let it slowly diminish inflammation and grow new nails.

If there is bleeding or broken skin, you should follow the doctor's advice to prevent infection.

When I was a child, I was injured by a machine weighing half a ton, and I was bruised on the spot, but there was no trauma or bone injury. An old doctor advised me to protect my injured nails and never touch their roots, so that they can grow new ones slowly.

Because new nails can't touch external forces when they grow again, otherwise, the nails will grow uneven.

Question 3: When I was a child, my toes were smashed, and now my nails are getting thicker and thicker. What should I do? The normal situation may be that the wound surface is overgrown with weeds after local nail injury, but it may also be that the wound surface has been infected by various infections, such as fungi. It is recommended to do a test to determine what the real reason is.
