Toenail fungus is an infection that gets in through cracks in your nail or cuts in your skin. It can make your toenail change colour or get thicker.
Anti-fungal creams and powders must be obtained from your GP or Pharmacist
Fungal nail infections can also be caused by walking barefoot in places where they can be spread easily such as communal showers, changing rooms and gyms or from damage to your nails from sports injuries and the like.
It is notoriously difficult to treat. Traditional treatments with medication and topical creams have limited success.
When left untreated, they can not only look unpleasant, but also spread to other nails causing further issues.
