While waiting to speak to a doctor, relieve your feet and keep them elevated.

If your regular doctor or foot protection team is not available, go to the nearest out-of-hours health center.

Leaving your foot problem untreated can lead to rapid decline and, for some people, put them at risk of losing their footing. So don’t delay in seeking medical help.
