Fungal Nail Infection (Tinea Unguium or Onychomycosis)
A fungal nail infection is caused by fungus invasion (Tinea Unguium or Onychomycosis). If left untreated, it leads to unsightly, larger nails that can be painful. This fungus can live on your skin without harming you, but if given the right conditions (they favour warm, wet settings), it can proliferate and cause illness.
The majority of fungal nail infections are harmless, although they can be difficult to treat. The illness can affect either your toe or fingernails, and it usually begins slowly with few symptoms. The nail, however, may become discoloured or distorted as the fungus multiplies and spreads, causing pain while walking or wearing tight shoes.
