Onychomycosis

Onychomycosis is a fungal infection of the toenails or fingernails that may involve any component of the nail unit, including the matrix, bed, or plate. Onychomycosis can cause pain, discomfort, and disfigurement and may produce serious physical and occupational limitations, as well as reducing quality of life.

In approximately half of suspected nail fungus cases there is actually no fungal infection, but only nail deformity.
