A fungal nail infection can affect one or all of the toenails. It leads to nails looking thickened and/or discoloured. A warm, dark and moist environments encourage fungi to develop.
Usually, a fungal skin infection (such as athlete’s foot) will precede any change to the nails. Therefore, it is important to seek help as soon as you suspect even a hint of a fungal skin infection.
Treating skin is much easier than treating infected nails!
