When you have a toenail fungal infection, the nail turns thick and either white, yellow, green, or brown. White streaks and spots may also appear on the infected nail. This medical condition is also known as onychomycosis. This becomes more common when the person becomes older. This condition is also quite tricky to cure. Toenail fungus infection is a widespread fungal infection that primarily affects the toes. The same fungus, however, also infects the fingernails. This occurs when the fungi get between the toenail and the toenail bed or the tissue underneath the toenail.
