Quick answer. Burning feet are most commonly caused by peripheral neuropathy – in Singapore, diabetes is the leading cause – along with vitamin B12 deficiency, nerve compression and skin conditions; sudden severe burning with a pale, cold foot is a circulation emergency needing urgent care.
Burning feet – a hot, tingling, prickling or stinging sensation in the soles or toes – is a surprisingly common complaint, often worse at night. For some people it is mild and occasional; for others it is persistent enough to disturb sleep. The sensation usually comes from irritated or damaged nerves rather than the skin itself, which is why understanding the underlying cause matters.
In Singapore, the single most important cause to consider is diabetes, which can damage the nerves in the feet over time. This guide explains the common reasons for burning feet, the warning signs that need quick attention, and which doctor is best placed to find and treat the cause.
At a glance
| Likely cause | Typical clues | What to do |
|---|---|---|
| Diabetic neuropathy | Known or undiagnosed diabetes; burning worse at night, both feet | See a doctor; check blood sugar and nerves |
| Vitamin B12 deficiency | Tingling, sometimes anaemia; vegetarian diet or older age | Blood test; treatable with supplements |
| Nerve compression | Localised burning, linked to a trapped nerve or footwear | GP or specialist review |
| Alcohol or thyroid | Heavy alcohol use, or thyroid symptoms | Address underlying cause |
| Circulation problem (urgent) | Sudden severe burning with a pale, cold or blue foot | Seek urgent care now |
Red flags: when burning feet need urgent care
Burning feet are usually a slow-developing nerve problem, not an emergency. But seek urgent care – go to A&E, or call 995 if severe – when burning feet come with signs that the blood supply or skin is in trouble:
- Sudden, severe burning with a foot that turns pale, cold, blue or numb – this can mean a blocked artery cutting off circulation, which is a limb emergency.
- A foot wound, ulcer, blackened skin, spreading redness or fever, especially if you have diabetes – this may be a serious infection that can progress quickly.
- Rapidly worsening weakness or numbness spreading up the legs – this needs prompt neurological assessment.
If you have diabetes, treat any new foot wound, colour change or infection seriously and seek care early, as nerve damage can mask the pain that would normally warn you.
Peripheral neuropathy and diabetes – the leading cause
The commonest reason for persistent burning feet is peripheral neuropathy – damage to the small nerves that supply the feet. In Singapore the leading cause of this is diabetes. Over time, high blood sugar damages these nerves, producing burning, tingling, numbness or pins and needles, usually in both feet and often worse at night.
Because burning feet can be the first noticeable sign of diabetes, anyone with new or unexplained burning in both feet should have their blood sugar checked. Good blood sugar control, foot care and specific medications can ease the symptoms and slow further nerve damage. Singapore’s Screen for Life programme makes checking for diabetes straightforward.
Vitamin B12 deficiency and other nutritional causes
A lack of vitamin B12 can damage nerves and cause burning, tingling feet, sometimes alongside tiredness or anaemia. It is more common in older adults, people on strict vegetarian or vegan diets, and those on certain long-term medications. The good news is that it is easily picked up with a blood test and often fully reversible with supplements or injections once identified. Other nutritional and metabolic issues can contribute too, which is why a doctor will often run a panel of blood tests when investigating burning feet.
Nerve compression, alcohol and thyroid causes
Nerve compression can produce a more localised burning – for example a trapped nerve in the foot or ankle, or pressure from tight footwear. Heavy alcohol use over years is a recognised cause of neuropathy, partly through direct nerve toxicity and partly through poor nutrition. An underactive or overactive thyroid can also affect the nerves. Each of these is identifiable and treatable once recognised, which is why pinning down the cause – rather than just treating the sensation – is the goal.
Skin causes such as athlete's foot
Not all burning feet come from the nerves. Athlete’s foot (tinea pedis), a fungal skin infection that thrives in Singapore’s warm, humid climate, can cause burning, itching, redness and peeling, typically between the toes or on the soles. Unlike nerve-related burning, it usually has visible skin changes and itch. It responds well to antifungal creams and good foot hygiene – keeping feet clean and dry, and changing out of sweaty shoes and socks. If the skin is broken, weeping or spreading, or if you have diabetes, see a doctor rather than self-treating.
Which specialist should you see?
For most people with burning feet, a GP is the right first stop. A GP can examine your feet, check your blood sugar and run blood tests for causes such as vitamin B12 deficiency or thyroid problems, treat skin conditions like athlete’s foot, and decide whether a specialist referral is needed.
Where the cause is nerve-related and needs detailed assessment – persistent or worsening neuropathy, or symptoms spreading up the legs – a neurologist can evaluate the nerves, including nerve studies, and confirm the diagnosis. Where diabetes or a hormonal cause is driving the problem, an endocrinologist manages blood sugar and the underlying metabolic condition, which is central to protecting the nerves long term. Throughout, keep the emergency rule in mind: sudden severe burning with a pale, cold foot is a circulation emergency – seek urgent care, calling 995 if it is severe.
