Toenail Fungus
Nail fungus is an infection that penetrates through cracks in the nail or cuts on the skin. It can cause your nail to change color or become thicker. It can hurt, too. Because the toes are often warm and damp, the fungus grows well there.
Different types of fungi and sometimes yeast affect different parts of the nail. If untreated, an infection can spread to other toenails, skin, or even nails.
