Burning, Tingling or Numb Feet: Is It Neuropathy?
Pins and needles, burning soles or numb toes that won't go away? The real causes (diabetes, low B12 and more), the tests that find them, and when it's urgent.
Burning soles at night. Toes that feel like they're wrapped in cotton. "Chiti chal rahi hai" tingling that never fully goes away. These are classic signs of peripheral neuropathy, which means the long nerves to your feet and hands aren't working properly. It is very common in India, mostly because of diabetes and low vitamin B12. The good news: the cause can usually be found with simple blood tests, and catching it early protects your feet.
How Neuropathy Usually Feels
- Both feet first, often starting in the toes and slowly moving up. Hands may follow later (doctors call it the "glove and stocking" pattern)
- Burning, tingling, pins and needles, or electric-shock jolts, often worse at night
- Numbness: not feeling the floor properly, or slippers slipping off without you noticing
- Feeling unsteady in the dark or on uneven ground
- In some people, cramps, weak ankles, or very dry, cracked skin on the feet
The Common Causes (and the Test for Each)
| Cause | Why it happens | Test that finds it |
|---|---|---|
| Diabetes | High sugar over years damages small nerves. The most common cause in India, sometimes found before diabetes itself is diagnosed | Fasting sugar, HbA1c |
| Low vitamin B12 | Common in vegetarians, people over 50, and people on metformin or acid-reducing tablets for a long time | Serum B12 |
| Underactive thyroid | Slows nerve repair | TSH |
| Alcohol | Direct nerve damage plus poor nutrition | History, liver tests |
| Kidney disease | Waste builds up in the blood | Creatinine, eGFR |
| Some medicines | Certain TB medicines (isoniazid, usually given with vitamin B6 for this reason), some chemotherapy and others | Medicine review |
| Infections | Leprosy (patchy numb skin, still seen in India), HIV | Skin check, specific tests |
Often one simple blood panel answers the question. If the cause still isn't clear, a nerve conduction study (a quick test of how fast signals travel along your nerves) helps a neurologist confirm it.
How Worried Should I Be?
| What you notice | What to do | |
|---|---|---|
| 🟢 Usually fine | Brief tingling after sitting cross-legged or sleeping on an arm, gone in minutes | Nothing. That is pressure on a nerve, not neuropathy |
| 🟡 See a doctor this week | Tingling, burning or numbness in both feet lasting weeks, slowly spreading | Book a consultation and get sugar, B12 and thyroid tested |
| 🔴 Emergency now | Sudden numbness or weakness on one side, face drooping or slurred speech | Possible stroke. Go to the nearest emergency now |
| 🔴 Emergency now | Weakness rising up both legs over hours to days, trouble walking or breathing | Possible Guillain-Barré syndrome. Go to hospital the same day |
| 🔴 Urgent | A foot wound, blister or blackening you can't feel, or a wound that isn't healing | See a doctor the same day. Numb feet hide injuries |
Myth vs Fact
| Myth | Fact |
|---|---|
| "Jhunjhuni is just weakness. A tonic will fix it." | Persistent tingling has a cause. Treating the cause (sugar, B12, thyroid) is what helps |
| "B12 injections cure every kind of neuropathy." | They help only when B12 is actually low. Test first |
| "Nothing can be done for nerve pain." | Controlling sugar slows damage, low B12 can be replaced, and doctors have specific nerve-pain medicines (ordinary painkillers often don't work) |
| "Walking barefoot is good for numb feet." | With numb feet it's risky. Wear soft, closed footwear, even at home |
Protect Your Feet Starting Today
- Look at your feet every night (use a mirror or ask family) for cuts, blisters, colour changes
- Test bath water with your elbow, not your foot. Numb feet burn easily
- Moisturise cracks, but not between the toes
- Well-fitting, soft footwear. Check inside shoes for stones before wearing them
- Keep sugar in your target range, and limit alcohol
Before You Consult, Note These
- When it started, and whether it is in one foot or both, and spreading or stable
- Your medicines, especially metformin, acid tablets, and TB or cancer medicines
- Whether you are vegetarian, and how much alcohol you drink
- Any recent reports: sugar, HbA1c, B12, thyroid, kidney
- Photos of any foot wound or skin patch
An online consultation works well for the first step. A doctor can review your symptoms and reports, order the right blood tests, and tell you whether you need an in-person nerve examination. Persistent tingling isn't "just age", so it's worth finding the cause early. (See our guides on vitamin B12 deficiency, diabetic foot care, and stroke warning signs.)
