What Is Nail Fungus?
Nail fungus, also known as onychomycosis, is a common fungal infection that affects the nails, typically starting at the edge or underneath the nail. Various fungi, including dermatophytes, yeasts, and molds, can cause it, leading to discoloration, thickening, and brittleness. Nail fungus thrives in warm and moist environments, making toenails more susceptible to infection than fingernails. The condition is not only a cosmetic concern but can also lead to discomfort, pain, and potential complications if left untreated.
