What Is Toenail Fungus?

Toenail fungus (onychomycosis) is a fungal infection caused by dermatophytes, yeasts, or molds.

These microbes grow in warm, moist places like gym showers, locker rooms, and tight shoes. They enter through tiny cracks in the nail or surrounding skin.

If left untreated, the infection worsens, leading to thick, discolored, and painful nails. Some people mistake it for nail trauma, but fungal infections require specific treatments.
