GlossaryNail Infection

fungal invasion of the nail causing discoloration and thickening

A nail infection, also known as onychomycosis or fungal nail infection, is a condition where fungi invade the nail bed, leading to discoloration, thickening, and crumbling of the nail. It is often caused by dermatophytes, yeasts, or molds and can affect both fingernails and toenails, making them appear unsightly and sometimes causing discomfort or pain.
