Your feet are mirrors of your health. Warning signs of health conditions can be dry skin, brittle nails, burning and tingling sensations in your feet, or feelings of cold, numbness, and discolouration.
If these occur, see a podiatrist, as they, along with your GP, will be able to pinpoint the cause.
Regular check-ups with your podiatrist are recommended, especially if you cannot look after your feet yourself and you have no one to help you.
Nails that grow too long can become infected and if you are diabetic - which has a higher risk factor as we age - infection can lead to more serious illness.
