What is Athlete's Foot?
A fungal infection of the skin between and under the toes.
Why does it matter?
It is easy to treat and easy to leave untreated, and untreated it provides a route in for bacterial infection.
What is the single most useful thing to do?
Continue treatment for one to two weeks after the skin looks clear.
What is the most common mistake?
Stopping treatment as soon as symptoms settle.
When should I see a doctor?
See a GP for spreading redness, warmth, swelling or pain in the foot or leg, which suggests cellulitis and needs antibiotics — particularly if you have diabetes or poor circulation. Any foot problem in diabetes should be assessed the same day.

Where this comes from
How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarised or generalised beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
