That hot, prickling sensation in the soles of your feet — especially when you lie down at night — is one of the more unsettling symptoms people quietly put up with for months. Many Pakistanis chalk it up to fatigue after a long day of standing, or blame the heat in Karachi or Lahore summers. Sometimes that’s all it is. But when the burning keeps coming back, or starts waking you up at night, it usually means something else is going on.
Pakistan carries one of the highest burdens of type 2 diabetes in the world, with over 33 million adults living with the condition according to the International Diabetes Federation (2021). Burning feet is one of the earliest nerve-related symptoms of diabetes, and it’s frequently missed or dismissed. Vitamin B12 deficiency — common in people eating predominantly plant-based desi diets or taking certain medications — is another major cause that goes undetected for years.
This guide covers the seven most common burning feet causes, the warning signs that need urgent attention, and what a doctor will typically check first.
What Causes Burning Feet?
Burning feet causes include peripheral neuropathy (nerve damage), diabetic neuropathy, vitamin B12 or B1 deficiency, hypothyroidism, chronic kidney disease, tarsal tunnel syndrome, and fungal skin infections such as athlete’s foot. In most cases, the burning is a symptom of an underlying condition rather than a problem with the foot itself, which is why identifying the root cause matters more than treating the sensation alone.
Burning Feet in Urdu
پاؤں میں جلن کی کیفیت اکثر اعصابی نقصان کی علامت ہوتی ہے، جو عام طور پر ذیابیطس، وٹامن بی 12 کی کمی، یا گردوں کی بیماری کی وجہ سے ہوتی ہے۔ پاکستان میں ذیابیطس کے مریضوں کی تعداد بہت زیادہ ہے، اس لیے پاؤں میں جلن کو نظرانداز نہیں کرنا چاہیے۔ اگر یہ جلن دو سے تین ہفتوں سے زیادہ رہے، رات کو بڑھ جائے، یا سُن پن کے ساتھ ہو، تو فوری طور پر کسی ڈاکٹر سے رجوع کریں۔ خون کے سادہ ٹیسٹ جیسے بی 12 اور تھائرائیڈ کی جانچ سے اکثر اصل وجہ معلوم ہو جاتی ہے۔
1. Diabetic Neuropathy: The Most Common Cause in Pakistan
Diabetic neuropathy is nerve damage caused by prolonged high blood sugar, and it is the leading cause of burning feet worldwide. According to the American Diabetes Association (2023), up to 50% of people with diabetes develop some form of peripheral neuropathy over their lifetime. In Pakistan, where blood sugar often goes uncontrolled for years before diagnosis, this figure is likely higher in clinical practice.
The nerves in the feet are the longest in the body, which makes them the first to show damage. The burning typically starts in the toes and soles, worsens at night, and may come with tingling, numbness, or a feeling that the feet are wrapped in something tight. One detail many Pakistani patients don’t know: Metformin, the most commonly prescribed diabetes tablet in Pakistan, can gradually lower vitamin B12 levels with long-term use, which adds a second layer of nerve risk on top of the diabetes itself.
If you have type 2 diabetes and notice any burning or tingling in your feet, report it to your doctor at the next visit. Early nerve damage can sometimes be slowed with better blood sugar control.
2. Vitamin B12 Deficiency: A Missed Cause in Desi Diets
Vitamin B12 is essential for maintaining the protective myelin sheath around nerve fibres. When B12 levels fall, that sheath breaks down and the exposed nerves begin misfiring, producing burning, tingling, or numbness that typically starts in the feet.
B12 deficiency is particularly common in Pakistan for two reasons. First, B12 is found almost exclusively in animal products — meat, eggs, dairy — and many Pakistani households eat predominantly roti, daal, and sabzi with limited meat intake. Second, people taking long-term Metformin, proton pump inhibitors (antacids like omeprazole), or those with gut absorption problems are at higher risk regardless of diet. A simple blood test can confirm the deficiency, and in many cases the burning improves significantly once B12 levels are restored through supplements or injections.
3. Peripheral Neuropathy from Other Causes
Peripheral neuropathy is the medical term for damage to the nerves outside the brain and spinal cord. Diabetes is the most common trigger, but neuropathy also develops from chronic kidney disease, hypothyroidism (underactive thyroid), certain chemotherapy drugs, and prolonged vitamin B1 (thiamine) deficiency.
The burning pattern in peripheral neuropathy follows what doctors call a “stocking distribution” — it starts at the toes and moves upward, affecting both feet roughly symmetrically. Symptoms often worsen at night because there are fewer distractions and lying down changes blood flow to the limbs. If the burning is accompanied by loss of sensation, difficulty walking, or muscle weakness, that points to more advanced nerve involvement and needs prompt evaluation.
4. Hypothyroidism: The Thyroid Connection
An underactive thyroid gland (hypothyroidism) can cause fluid retention in the tissues, which puts pressure on peripheral nerves and produces a burning or tingling sensation in the feet. This is a less obvious cause that is often missed when doctors focus only on diabetes and B12.
Hypothyroidism is more common in women, and Pakistan has a significant burden of thyroid disorders, particularly in areas with low dietary iodine intake. Other symptoms that accompany thyroid-related burning feet include fatigue, weight gain, cold intolerance, and constipation. A TSH (thyroid-stimulating hormone) blood test is the standard screening tool and costs roughly Rs. 800 to Rs. 1,500 at most diagnostic labs in Lahore and Karachi.
5. Chronic Kidney Disease
When the kidneys stop filtering waste products efficiently, those toxins accumulate in the blood and act as nerve poisons. This produces a burning or prickling sensation in the feet known as uremic neuropathy. Chronic kidney disease often develops silently alongside diabetes and hypertension — two conditions that are extremely prevalent in Pakistan.
Burning feet caused by kidney disease tends to be accompanied by other symptoms: swelling in the legs and ankles, fatigue, reduced urine output, or foamy urine. If you notice swollen feet alongside the burning sensation, that combination warrants a kidney function test (creatinine and urea) without delay.
6. Tarsal Tunnel Syndrome
Tarsal tunnel syndrome is a nerve compression condition, similar to carpal tunnel syndrome in the wrist but affecting the tibial nerve as it passes through a narrow channel on the inside of the ankle. Compression of this nerve produces burning, tingling, and shooting pain in the sole of the foot, often on one side only.
This condition is more common in people with flat feet, those who stand for long hours on hard floors (common in factory and retail work in Pakistani cities), and those who wear tight or unsupportive footwear. Unlike diabetic neuropathy, tarsal tunnel syndrome typically affects one foot more than the other and may worsen with prolonged standing rather than at night.
7. Athlete’s Foot and Skin Causes
Athlete’s foot (tinea pedis) is a fungal infection of the skin between the toes and on the soles. It produces itching, peeling, and a burning sensation that is usually more superficial than the deep nerve-related burning described above. It’s common in Pakistan during the monsoon months when feet stay damp inside shoes for hours.
Other skin causes include contact dermatitis from synthetic shoe materials or chemical dyes in cheap plastic chappals, and eczema. These are generally the least serious causes and respond well to antifungal creams or avoiding the irritant, but they should not be self-treated for more than a week without improvement.
Burning Feet Causes vs. Symptoms: A Quick Comparison
| Cause | Typical Pattern | Both Feet? | Worse at Night? |
|---|---|---|---|
| Diabetic neuropathy | Toes and soles, stocking distribution | Yes | Yes |
| Vitamin B12 deficiency | Toes and soles, tingling | Usually yes | Yes |
| Tarsal tunnel syndrome | Sole and inner ankle | Usually one side | Sometimes |
| Hypothyroidism | Diffuse, with swelling | Yes | Variable |
| Chronic kidney disease | Diffuse, with leg swelling | Yes | Yes |
| Athlete’s foot | Between toes, skin surface | Often both | No |
| Peripheral artery disease | Cramping, cold feet | Yes | No (worse on walking) |
Warning Signs That Need Urgent Attention
Most burning feet causes are not emergencies, but some signs mean you should see a doctor promptly rather than waiting. Seek medical attention if the burning is accompanied by open sores or wounds on the feet that are slow to heal, sudden loss of sensation in one or both feet, one-sided weakness or difficulty walking, rapidly spreading redness or warmth (which can indicate infection), or if you have diabetes and notice any new foot symptom at all.
Persistent burning that has lasted more than two to three weeks without an obvious cause — such as new shoes or a long day of walking — also deserves a proper evaluation. A neurologist in Pakistan can assess nerve function through a physical examination and, if needed, nerve conduction studies.
Key Takeaways
- Burning feet causes are most commonly nerve-related: diabetic neuropathy accounts for the majority of cases, with up to 50% of people with diabetes developing peripheral neuropathy over their lifetime, according to the American Diabetes Association (2023).
- Vitamin B12 deficiency is a common and reversible cause of burning feet in Pakistan, particularly in people eating predominantly plant-based diets or taking long-term Metformin.
- Hypothyroidism and chronic kidney disease are two systemic causes that are frequently missed when only diabetes is considered.
- Tarsal tunnel syndrome typically affects one foot more than the other and worsens with standing, unlike diabetic neuropathy which is usually symmetrical and worse at night.
- A TSH blood test and B12 level are low-cost, widely available tests in Pakistan (Rs. 800 to Rs. 1,500 at most labs) that can rule out two of the most treatable causes.
- Open sores, sudden numbness, or rapidly spreading redness alongside burning feet require prompt medical evaluation, not home management.

Finding the right doctor for a symptom like burning feet can be confusing because the cause could sit with an endocrinologist, a neurologist, or a general physician depending on what’s driving it. If you have diabetes or suspect a blood sugar or thyroid issue, an endocrinologist in Pakistan is the right starting point. For nerve-related symptoms without a clear metabolic cause, a neurologist can assess nerve function directly.
Marham connects you with verified specialists across Karachi, Lahore, Islamabad, and other cities through online and in-person consultations. A short online consultation typically takes 15 to 20 minutes and can help you decide which tests to get first, saving you the cost and time of unnecessary investigations.
Frequently Asked Questions
What causes burning feet?
Burning feet are most commonly caused by peripheral neuropathy, which is nerve damage linked to diabetes, vitamin B12 deficiency, or kidney disease. Other causes include hypothyroidism, tarsal tunnel syndrome, and fungal skin infections. Because the causes vary widely, a blood test and clinical examination are needed to identify the specific reason.
What vitamin deficiency causes burning feet?
Vitamin B12 deficiency is the most common vitamin-related cause of burning feet. B12 is needed to maintain the protective coating around nerve fibres, and when levels drop, nerves begin misfiring and produce burning or tingling sensations. Deficiencies in vitamin B1 (thiamine) and vitamin B6 can also contribute to nerve-related foot symptoms.
Can burning feet be a sign of diabetes?
Yes, burning feet can be an early sign of diabetic neuropathy, which is nerve damage caused by prolonged high blood sugar. It often starts in the toes and soles and worsens at night. Anyone with diabetes who notices new burning or tingling in the feet should report it to their doctor promptly.
Is burning feet serious?
Burning feet can range from a minor issue — such as a fungal infection or ill-fitting shoes — to a sign of a serious underlying condition like uncontrolled diabetes or kidney disease. Persistent burning lasting more than two to three weeks, or burning accompanied by numbness, wounds, or swelling, should be evaluated by a doctor.
How do I stop my feet from burning at night?
Relief depends on the cause. If diabetic neuropathy is responsible, better blood sugar control is the most effective long-term step. For B12 deficiency, supplementation often improves symptoms within weeks. Cooling the feet with a damp cloth, avoiding tight socks at night, and elevating the legs slightly can provide temporary comfort while the underlying cause is being treated.
Can kidney disease cause burning feet?
Yes, chronic kidney disease can cause burning feet through a process called uremic neuropathy, where waste products that the kidneys fail to filter accumulate in the blood and damage peripheral nerves. This is often accompanied by leg swelling, fatigue, and changes in urine output.
When should I see a doctor for burning feet?
See a doctor if the burning has lasted more than two to three weeks, if it is getting worse, or if it is accompanied by numbness, open sores, swelling, or difficulty walking. People with diabetes should not wait — any new foot symptom in a diabetic patient warrants prompt medical review to prevent complications.
Conclusion
Burning feet is a symptom, not a diagnosis, and the underlying cause can range from something as straightforward as a vitamin deficiency to something that needs ongoing medical management like diabetic neuropathy or kidney disease. In Pakistan, where diabetes and nutritional deficiencies are both highly prevalent, burning feet deserves more attention than it typically gets. A few targeted blood tests — blood sugar, B12, TSH, and kidney function — can identify the most common causes quickly and point toward the right treatment. The sooner the cause is found, the better the chances of preventing permanent nerve damage.
