During the day you barely notice it. Then you get into bed, the house goes quiet, and your feet start to burn, as if you’d been standing on hot pavement. Sometimes it tingles. Sometimes you stick your feet out from under the covers just to cool them down.
Burning feet at night are most often a sign of irritated or damaged nerves in the feet, a condition called peripheral neuropathy, and diabetes is one of the most common causes. But it is far from the only one. Low vitamin B12, heavy drinking, kidney or thyroid problems, some medicines, and even athlete’s foot can do it. Several of these can be checked with simple blood tests, and some are very treatable.
What’s going on in your nerves
The long nerves that reach your feet carry messages about touch, temperature, and pain. When they’re damaged, they can misfire and send pain signals even when nothing is hurting your feet. The National Institute of Neurological Disorders and Stroke (NINDS) describes burning, tingling, numbness, and sharp pains as common symptoms of peripheral neuropathy, often starting in the feet.
Why it feels worse at night
Many people notice the burning most at bedtime. During the day, walking, talking, and work keep your brain busy. At night, with fewer distractions, the nerve signals are harder to ignore. Warm blankets can add to it too.
Common causes, and the clues that point to each
Mayo Clinic lists a wide range of possible causes for burning feet. This table groups the most common ones with the clues to mention to your doctor:
| Possible cause | Clues that may point to it | What a doctor may check |
|---|---|---|
| Diabetes or prediabetes | Thirst, frequent urination, family history, extra weight | Blood sugar or A1C test |
| Low vitamin B12 | Tiredness, vegetarian or vegan diet, older age, weight-loss surgery, long-term use of certain medicines such as metformin or acid reducers | B12 blood test |
| Heavy alcohol use | Regular drinking over years | Exam and blood tests |
| Kidney disease | Swelling, changes in urination, high blood pressure | Kidney function tests |
| Underactive thyroid | Feeling cold, tired, constipated, weight gain | Thyroid blood test |
| Medicines | Burning started after a new drug, such as some chemotherapy | Review of your medicines |
| Athlete’s foot | Itching, peeling, or cracked skin between the toes | Skin exam |
| Pressure on a nerve near the ankle (tarsal tunnel) | Burning mostly on the sole, worse with standing or walking | Physical exam |
Sometimes no cause is found, which doctors call idiopathic neuropathy. Even then, treatment can help with the symptoms.
Track it for a week before your appointment
A short log gives your doctor much more to work with than “my feet burn sometimes.” Copy this table into a notebook or your phone:
| Date | When it burned (time of day) | How bad (0–10) | Tingling or numbness? | Where (toes, sole, whole foot) | Alcohol or new medicines that day |
|---|---|---|---|---|---|
| Oct 2 | 10 p.m. to midnight | 6 | Tingling in toes | Both soles | 2 glasses of wine |
Patterns like “both feet, worse at night, slowly creeping up” or “one foot, worse when walking” help point your doctor in the right direction.
Things that may ease the burning tonight
These won’t fix the cause, but they may make nights more bearable:
- Keep your feet cool. Try a lighter blanket or let your feet stick out from the covers.
- A short soak in cool water for 10 to 15 minutes before bed. Avoid ice or very cold water, which can harm skin, especially if your feet are numb.
- Breathable cotton or moisture-wicking socks, and shoes that don’t squeeze your toes.
- Check your feet for blisters, cuts, or red spots, especially if they feel numb.
- Ask about pain relief. Over-the-counter pain relievers don’t help everyone with nerve pain. Your doctor can suggest options, including prescription medicines made for nerve pain.
Don’t guess about B12 or other supplements
Low vitamin B12 is a real and treatable cause of nerve damage. The NIH Office of Dietary Supplements notes that older adults, people who don’t eat animal foods, people who have had weight-loss surgery, and people taking certain medicines are more likely to be low. But tingling feet have many causes, and high-dose supplements can hide other problems. A blood test first is the safer route.
Which situation sounds like you?
If you have diabetes
Burning feet may be diabetic neuropathy. Daily foot checks become important, because numb feet don’t warn you about injuries. Our next guide on diabetic neuropathy and foot care shows you how.
If you’ve never been tested for diabetes
Ask your doctor for a blood sugar or A1C test. Nerve symptoms are sometimes the first clue.
If you drink most days
Alcohol can damage nerves over time. Cutting back is one of the most direct things you can do, and your doctor can help.
If your legs also feel restless or jumpy at night
That can be a different problem. Our guide to restless legs at night explains how to tell them apart.
When burning feet need a checkup
See a doctor if burning feet last more than a few weeks, keep getting worse, or spread up your legs. Get care promptly if you have:
- A cut, blister, or sore on your foot that isn’t healing, or looks red, warm, or swollen
- Numbness or weakness that is spreading or makes it hard to walk
- Burning that started suddenly, especially after a new medicine
- Diabetes and any new foot wound
Start tonight
Before bed, look at both feet in good light, top and bottom. Then start the one-week log above. At your appointment, bring the log and ask specifically about a blood sugar test, a B12 test, and a review of your medicines. Those three checks rule in or out several of the most common causes in one visit.
