What are the early symptoms of onychomycosis?

Onychomycosis is a fungal infection of the fingernails or toenails.

In the beginning, the surface of the nail will lose its luster and become uneven, and the tip of the nail will thicken and turn grayish-yellow and cloudy.

Further, the fungus can infect where the fingernail connects to the knuckle, causing it to become rough, thick, uneven, or broken.

Eventually, the entire nail will be damaged, turning sallow, taupe, the deck may completely fall off, and the nail bed will thicken and scale.

Onychomycosis is divided into different types according to the location and degree of fungal invasion of the nail.

Onychomycosis can be cured by pulling it out?

So, if your own finger/toenails and the skin around the nails are not broken, and briefly shake hands with the patient, the possibility of infection is very small.

But if you live with someone with onychomycosis for a long time, you still need to take care to prevent infection.
