What causes nail and meat separation?

Nail and flesh separation may be caused by onychomycosis caused by fungal infection of the nail bed. When showing onychomycosis, the most obvious symptom is that the color of the nail will show gray or black, and the nail bed will also become thin, and may also show symptoms of empty under the nail, all caused by onychomycosis. However, it is not ruled out that skin diseases caused by excessive cutin under the nail bed, such as onychomycosis, are caused. In this case, it is still necessary to go to the hospital for examination in time, and apply topical drugs under the guidance of professional doctors. However, it is also necessary to do personal care work in peacetime, and wear shoes or socks with good ventilation.
