Burning Feet at Night: B12, Diabetes and What Cools Them
Your feet feel like they are sitting an inch above a tawa, right around the time you are trying to fall asleep. That is paon ki jalan, and before you reach for another cold-water soak, it is worth asking why it is happening at all.
Quick facts
- Common causes: vitamin B12 deficiency, diabetes-related nerve damage, thyroid problems, tight or synthetic footwear, athlete’s foot
- Cooling method: lukewarm to cool (not ice-cold) water soak, 10 to 15 minutes
- Tests to ask for: fasting blood sugar or HbA1c, serum B12, TSH
- See a doctor if: burning has lasted more than 2 to 3 weeks, or you notice numbness or tingling with it

Burning feet at night is one of those complaints people treat as a nuisance rather than a signal. It is not always serious. Sometimes it is nothing more than synthetic socks trapping heat all day and the skin finally cooling down and tingling as blood flow shifts at rest. But when it happens most nights, for weeks, it usually has a cause worth naming rather than just soothing.
Why paon jalte hain: the short list of real causes
Four causes explain most cases seen in general practice, and they are worth separating because the fix is different for each one.
Vitamin B12 deficiency
B12 is needed to keep the coating around nerves healthy. Low levels, common in people who eat little meat, egg or dairy, and in anyone on long-term metformin, can cause a burning or pins-and-needles feeling that starts in the feet and can move up the shins over months. It is one of the few causes of burning feet that is genuinely fixable once caught.
Diabetes and peripheral neuropathy
High blood sugar over years damages the small nerves in the feet first, because they are the longest nerves in the body and the most exposed to sustained sugar damage. The burning is often worse at night, sometimes with numbness in a stocking pattern, meaning it stops sharply at the ankle. Anyone with diabetes and new foot burning needs a foot check, not just a home remedy.
Thyroid imbalance
Both an underactive and, less often, an overactive thyroid can produce burning or tingling in the feet, usually alongside other signs such as fatigue, hair thinning, or unexplained weight change.
Tight shoes, synthetic socks and fungal infection
Closed shoes worn all day in Pakistan’s heat, especially synthetic-lined ones, trap sweat and heat. Add athlete’s foot (a fungal infection that thrives in that same damp warmth) and the itching and burning combination gets worse by evening. This cause responds fastest to a change in footwear and foot hygiene.
The cooling soak, done properly
A foot soak will not fix a B12 deficiency or diabetic nerve damage, but it genuinely helps you sleep through a bad night, and it costs nothing.
- Fill a tub or bucket with plain tap water, cool to lukewarm (around 20 to 24°C). Avoid ice water; a sudden temperature shock can worsen nerve sensitivity in some people rather than calm it.
- Soak both feet for 10 to 15 minutes, sitting rather than standing.
- Pat dry thoroughly, especially between the toes, since damp skin between toes invites fungal growth.
- Apply a plain, fragrance-free moisturiser if the skin feels dry or cracked, but skip it if you suspect athlete’s foot; keep that area dry instead.
- Elevate the feet on a pillow for 15 minutes before sleep. This can reduce the pooling sensation some people describe as heat building up.
What elders did, and why some of it still makes sense
Older household advice for jalte hue paon usually involved standing on a cool stone or mud floor, or applying mehndi paste to the soles. Mehndi has a cooling reputation in Unani thought and is described there as having a thanda (cold) quality, useful for the sensation of internal heat. None of this changes a B12 count or a blood sugar reading, but the cooling contact itself can genuinely ease discomfort for an hour or two, which is exactly what it was meant to do. Treat it as comfort, not correction.
Myth: burning feet always means “garmi” in the body
Myth: burning feet always means the body has excess heat that needs to be cooled from inside with foods or pastes. In reality, this is a nerve or circulation symptom far more often than a heat-balance one, and treating only the sensation while ignoring blood sugar or B12 can let an underlying problem run for years unchecked. Cooling remedies can ease the feeling for a night. They cannot repair a nerve that is already being damaged by sugar or deficiency.
When it is more than tired feet
Get this checked rather than soaked away if: you have diabetes and are noticing new burning or numbness in the feet; the sensation has lasted more than 2 to 3 weeks; there is numbness, weakness, or loss of balance along with the burning; you notice a foot ulcer, wound, or colour change (diabetics especially should never ignore a foot sore); you are pregnant and develop new burning feet, which needs a doctor’s review rather than self-treatment; or the burning came on suddenly and severely rather than building gradually. A fasting sugar or HbA1c, a B12 level, and a thyroid panel (TSH) are the three tests worth asking for; they are inexpensive and cover most causes in one sitting.
What the tests actually look for
A fasting blood sugar above 126 mg/dl on two separate occasions, or an HbA1c of 6.5 percent or higher, points toward diabetes as a likely contributor. A serum B12 level below roughly 200 pg/ml is generally considered deficient, though some doctors treat borderline levels between 200 and 300 if symptoms fit, since the lab cutoff isn’t perfectly precise for everyone. TSH above the normal range (usually around 4.5 to 5 mIU/L depending on the lab) suggests an underactive thyroid worth discussing further. None of these numbers are something to interpret alone; take them to whichever doctor ordered the tests and let them explain what, if anything, needs treatment.
Footwear and daily habits that actually help
Switch to cotton socks over synthetic ones, especially in Pakistan’s summer months. Give shoes at least a day to air out and dry between wears rather than wearing the same pair two days running. If you stand for long hours at work, a short seated break with feet up mid-shift makes a real difference by evening. None of this is glamorous advice, but it addresses the mechanical half of the problem while the tests sort out the rest.
Try this tonight
Soak feet for 10 minutes in cool water, dry well between the toes, then sleep with feet slightly elevated on a folded blanket. If tonight is better than most nights, footwear and heat are a bigger part of your problem than a deficiency, though it is still worth getting the blood tests done if the pattern repeats.
FAQ
Is burning feet always related to diabetes?
No. It is one of several possible causes, alongside B12 deficiency, thyroid problems, and simple footwear heat. Diabetes is common enough that it should always be ruled out, but it is not the only explanation.
Can I take B12 tablets without a blood test first?
It is better to test first. B12 is water-soluble and rarely harmful in normal doses, but knowing your actual level helps a doctor judge whether you need tablets, injections, or just dietary change.
Does mehndi paste actually cool the feet?
It gives a real, if temporary, cooling sensation through contact and evaporation. It has no effect on the underlying nerve or circulation issue causing the burning.
Should I avoid spicy food if my feet burn at night?
There is no established link between spicy food and burning feet. The two forms of “heat” work on different mechanisms in the body.
Burning feet is a common, usually treatable complaint once the actual cause is named. Start with the two cheapest tests, a fasting sugar and a B12 level, before assuming it is something you just have to live with. If foot care and diet alone aren’t shifting things, the Desi Remedies approach here is always the same: soothe tonight, but find out why for the long run.
