If you have ever wondered what our feet tell us about our health, the useful answer is: sometimes quite a lot.
Persistent coldness, swelling, numbness, nail changes, cracked skin or pain can be clues that something beyond footwear deserves attention. None diagnoses a condition by itself. The telling detail is change — especially something new, persistent, one-sided or painful.
Rachel Jones, Pharmacy Superintendent at Superdrug, stresses knowing your own baseline.
“Your feet can reveal a surprising amount about your health. While dry skin or the occasional ache is usually nothing to worry about, persistent changes to your feet can sometimes be an early sign of an underlying health condition. The key is knowing what’s normal for you and recognising when something changes”
Cold Feet Can Signal Circulation or Thyroid Problems
Cold feet are usually mundane. But persistent coldness alongside pain on walking, numbness or a change in skin colour deserves more attention. Reduced blood flow can be associated with peripheral arterial disease; an underactive thyroid can increase sensitivity to cold; diabetes can affect nerves and circulation.
“Cold feet aren’t always caused by chilly weather. They can simply be down to poor circulation on a cold day, but if your feet are consistently cold, particularly if it’s accompanied by pain when walking, numbness or changes in skin colour, it could be a sign of reduced circulation from a thyroid disorder or peripheral arterial disease.
People with diabetes may also experience cold feet due to nerve damage or circulation problems, so it’s important not to ignore persistent symptoms. If diabetes is a concern, Superdrug’s Diabetes Blood Test can help assess your blood sugar levels over the past two to three months, providing a clearer picture of your risk.”
Swollen Feet and Ankles: The Pattern Matters
Feet and ankles can swell after long periods of standing, travel or during pregnancy. Sudden swelling, swelling on one side, or swelling that does not settle after rest is more concerning than familiar end-of-day puffiness.
“Swollen feet after a long day on your feet, travelling or during pregnancy are usually nothing to worry about. However, swelling that appears suddenly, only affects one foot, or doesn’t improve after rest could be a sign of an underlying issue such as poor circulation, a blood clot or heart, kidney or liver problems. If the swelling is persistent or accompanied by pain, redness or breathlessness, it’s important to seek medical advice.”
Toenail Changes Can Offer Useful Health Clues
Thick, yellow or brittle nails are commonly associated with fungal infection. Changes in colour, shape or texture can have other causes, while an unexplained dark streak warrants professional assessment rather than bathroom-mirror detective work.
“Your toenails can often provide clues about your overall health. Thickened, yellow or brittle nails are commonly caused by a fungal nail infection, which is very treatable. However, changes in nail colour, shape or texture can occasionally be linked to nutritional deficiencies or other medical conditions.
A dark streak that appears without injury should always be assessed by a healthcare professional, as in rare cases it can be a sign of skin cancer under the nail.”
Numbness, Tingling and Burning Should Not Become Background Noise
Pins and needles after sitting awkwardly are ordinary. Repeated numbness, tingling or burning is different. Diabetes-related nerve damage is one possible cause; vitamin deficiencies and neurological conditions are others.
“Occasional pins and needles after sitting awkwardly are completely normal. However, frequent numbness, tingling or burning sensations in your feet shouldn’t be ignored.
These symptoms can be associated with nerve damage, particularly in people with diabetes, but they can also be linked to vitamin deficiencies or other neurological conditions. If symptoms persist, it’s worth getting them checked.”
Cracked Heels Matter More When They Will Not Heal
Dry, cracked heels are usually a skin-care problem. Deep, painful cracks or skin that will not heal deserve more attention, particularly for people with diabetes, where foot wounds can carry greater risk.
“Dry, cracked heels are incredibly common, particularly during the summer when we’re wearing sandals more often. In most cases, they’re caused by dry skin and can be managed with regular moisturising.
However, if cracks become deep, painful or aren’t healing properly, particularly if you have diabetes it’s important to seek advice. People with diabetes are at greater risk of foot complications, and even small breaks in the skin can become infected if left untreated.”
Pain When Walking May Be More Than Tired Feet
Soreness after a long day or badly fitting shoes is easy to explain. Pain that keeps returning, limits daily activity or sits around the base of the big toe can point towards a bunion.
“It’s not unusual for your feet to feel sore after a long day on them or if you’ve been wearing shoes that rub or don’t fit properly. However, persistent pain, particularly around the base of the big toe, could be caused by a bunion.
Bunions often develop gradually and can make walking uncomfortable or finding well-fitting shoes more difficult. If the pain is ongoing or affecting your daily activities, it’s worth seeking advice to discuss ways to manage your symptoms.”
The broader lesson in what our feet tell us about our health is pleasingly unglamorous: notice change, persistence and combinations of symptoms.
Feet are poor conversationalists, but when the same message keeps arriving, it is probably time to listen.
