Nail Infection

Nail infections are common and usually affect the toenails more than the fingernails. They are often caused by fungi and can make nails thick, discoloured, and sometimes painful. Treating a nail infection early can stop it from spreading or getting worse.

What is a Nail Infection?

A nail infection, also known as fungal nail infection, happens when fungi grow under or on the nail. It can start as a white or yellow patch and slowly spread, making the nail thicker, brittle or crumbly. Nail infections can spread from person to person and often happen if your feet stay warm and damp for a long time. They are more common in older people, those with diabetes or weak immune systems, and people who often wear tight shoes or walk barefoot in shared showers.

How to manage nail infections

  • Keep nails short, clean and dry
  • Avoid walking barefoot in public showers or changing rooms
  • Wear clean, breathable socks and shoes
  • Use antifungal creams, sprays or nail lacquers as advised
  • See a pharmacist or GP if the infection doesn’t improve
  • Do not share nail clippers or shoes with others
  • Consider oral antifungal medicine for more serious infections
  • Be patient, as nail infections can take months to fully clear

Common symptoms
