Chinese medicine is called "goose claw wind", and now it is called onychomycosis, which is caused by a large class of microbial infections called pathogenic fungi. The clinical symptoms of onychomycosis are as follows:

1. The diseased nail is thickened and discolored (gray or yellow), the deck of the diseased nail loses luster, the surface is uneven, the deck becomes brittle and damaged, and sometimes the deck is separated from the nail bed.

Second, the deck of patients with onychomycosis is often uneven and black, and the deck often shrinks slightly without thickening, often accompanied by paronychia.

The most common pathogen of onychomycosis is Trichophyton rubrum.

Four, there are two types of onychomycosis. One is the white nail, which often starts from the nail root, and small white spots appear on the deck surface, which gradually expand, resulting in the deck softening and sinking.

Another kind of damage starts from the free edge and side wall of the nail, which makes the small depression or horizontal groove of the nail appear on the deck and gradually develops into brittleness, fragility, thickening and brown inside. The accumulation of debris under nails often makes nails empty and tilt from the nail bed and deck.

The surface is uneven, rough and dull.
