Why Do My Feet Burn at Night?

You get into bed. The house goes quiet. And within twenty minutes your feet start to burn — a hot, electric, prickling feeling that was not there all day.

Almost everyone who has this asks the same question first: why only at night?

Why it gets worse when you lie down

Three ordinary things line up at bedtime, and together they turn the volume up.

There is nothing else competing for your attention. During the day your brain is busy. Pain signals arrive and get filtered out. In a dark, silent room there is nothing to filter them with, so the same signal feels much louder. This is not imagination — it is how attention works.

Your feet warm up under the covers. Warmth makes irritated nerve endings fire more readily. It is the same reason a sunburn stings more in a hot shower.

Circulation changes when you stop moving. All day, walking pushes blood back up from your feet. Lying still removes that pump. Nerves sitting at the end of a sluggish blood supply complain.

What usually lies behind it

Burning feet at night most often comes down to the small nerves in the feet not being in good condition. The common reasons are:

  • Blood sugar. Long-running high blood sugar is the single most common cause of small-nerve trouble in the feet. Many people discover their blood sugar problem because of their feet.
  • B vitamins. B12 in particular. Deficiency is common after 60, and commoner still in people taking metformin or long-term acid reducers.
  • Circulation. Narrowed vessels mean less blood reaching the far end of the body.
  • Alcohol. Regular drinking damages small nerves directly, and quietly.
  • Thyroid, kidney function, and some medications — including a few chemotherapy drugs and certain antibiotics.

Often more than one of these is in play at once.

Please see a doctor if

This article is about the slow, long-standing kind of burning. Some things need an appointment this week rather than a plan:

  • The numbness or weakness is new, sudden, or getting worse quickly
  • It is only on one side
  • You have an open sore or wound on the foot that is not healing
  • You are also unsteady on your feet, or falling

And if this has never been looked at, ask for blood tests: fasting glucose or HbA1c, B12, and thyroid function. Those three explain a large share of cases, and two of them are straightforward to correct.

Things that tend to help the nights

None of this reverses nerve damage. Anyone who tells you otherwise is selling something. But nerves need three things — circulation, nutrition and warmth handled correctly — and most people are missing at least one.

A warm (not hot) foot soak, ten minutes, an hour before bed. Warm water widens the vessels and moves blood into the feet. Test the temperature with your hand or elbow, never with your feet — if your sensation is reduced you can scald yourself without noticing. If you have diabetes, this matters a great deal.

Self-massage in the right direction. Stroke firmly from the toes toward the heart, not away from it. Most people instinctively do the opposite. You are helping fluid and blood return, so direction matters.

Elevate your feet for fifteen minutes in the evening — on a cushion, above hip level — well before you get into bed, not at bedtime.

Keep the bedroom cool and the feet out from under heavy covers. Many people find a cotton sheet over the feet and a blanket only up to the knees makes a noticeable difference within a few nights.

Look at the last four hours of your day. Alcohol in the evening and blood sugar swinging after a late, heavy meal both make the burning worse. This one takes a week to notice, but people who change it tend to keep the change.

What to expect

Sleep is usually the first thing that shifts — often within a couple of weeks. The burning itself moves more slowly, and for some people it does not move much at all. That is the honest picture, and it is worth knowing before you start.
