Toenail fungus also goes by the name onychomycosis. It is a common fungal infection that affects the toenails. Its most noticeable symptom is a white, brown, or yellow discoloration of one or more toenails. This infection may spread to the other nails and cause them to crack and thicken. This is a challenging condition to treat.
