Burning feet is one of those symptoms that are always described in the same way , "as if I were walking on hot sand", "my sole burns in the evening", "I have to get my foot out from under the covers", and it almost never starts in the foot.
This article is about understanding where it comes from, because the answer completely changes what it makes sense to do.
First question: one foot or both?
This is the question that splits the field in two, and it is worth answering straight away.
Both feet, symmetrical, and the problem rises from the feet upwards. This pattern, which textbooks call "stocking-type", is not a foot problem: it is a sign that involves the whole peripheral nerve system. By far the most frequent cause is metabolic, in particular diabetic neuropathy, the most common form of peripheral neuropathy. It is also worth adding that about half of diabetic neuropathies can present asymmetrically, so symmetry helps but is not an absolute rule (Diabetic Peripheral Neuropathy: StatPearls, 2024).
If this describes you, the useful step is not an exercise: it is a blood test. Blood glucose, glycated haemoglobin, vitamin B12 and thyroid function are the tests usually checked first, and your GP can order them.
One foot only. Then you look for a precise point along the path of the nerve, and where to look depends on where it burns.
Where it burns: the map that guides you
The heel, on the inner side, with a burning pain. Here there is an underestimated diagnosis worth knowing about. A review published in Neurological Sciences in 2025 calls it "the hidden culprit of chronic heel pain": entrapment of Baxter's nerve, the first branch of the lateral plantar nerve. It accounts for up to 20% of cases of chronic heel pain, is frequently mistaken for plantar fasciitis, and the burning quality together with neurological symptoms is what sets it apart (Baxter's nerve: the hidden culprit of chronic heel pain, Neurological Sciences, 2025).
Put simply: if you have been told it is plantar fasciitis, you have done months of stretching, and the heel still burns rather than giving the sharp pain of the first steps in the morning, the diagnosis deserves to be looked at again.
The sole, with tingling running towards the toes, and a tender spot behind the inner ankle bone. This is the picture that suggests tarsal tunnel syndrome, meaning irritation of the posterior tibial nerve as it passes through the canal behind the ankle. It is also referred to as "posterior tibial nerve neuralgia" (Tarsal Tunnel Syndrome: StatPearls, 2026).
Between the third and fourth toes, like an electric shock, worse in tight shoes. This is the typical presentation of a Morton's neuroma, and it characteristically changes when you take the shoe off and massage the forefoot.
The top of the foot, after a day on your feet or tightly laced shoes. This is often irritation of superficial nerve branches from external compression: the case where changing the laces solves more than any therapy would.
Why it is worse at night
Almost everyone notices this, and it has a simple explanation: at night the background noise is gone. During the day the foot receives a constant stream of information (the shoe, the floor, the weight, the movement), and that flow partly masks the abnormal signal. In bed all of this disappears and only the burning remains.
This is also why burning that comes mainly at night points more towards the nerve than towards mechanical overload, which typically gets worse while you walk and eases when you stop.
What makes sense to do, in order
- Establish whether it is one foot or two. This decides everything else.
- If it is two, get the tests done. This is the step you do not skip, and it is not something a physiotherapist does.
- If it is one, map where it burns and look for the point along the nerve: inner heel, behind the ankle bone, forefoot, top of the foot.
- Look at your shoes. Lacing, width of the forefoot, heel height: in many compressive pictures this is the variable that gets sorted first, and for free.
- Keep moving anyway. In metabolic neuropathies regular physical activity is part of the treatment, not an extra.
When you need a doctor, not an exercise
- A wound or a blister that does not heal on a foot that feels little: this is the situation that leads to ulcers, and it needs to be seen straight away.
- Loss of sensation or strength, or a foot that "drops" when you walk.
- The foot changes colour or temperature, or the burning comes with pain at rest: this is also where circulation is assessed.
- Symmetrical burning that spreads up towards the legs, or that also appears in the hands.
- Onset after a new medication, chemotherapy, or a marked weight loss.
What we can do, and what we cannot
We do not treat metabolic neuropathy, and we do not make diagnoses: that is the job of a doctor. What can be done in a free twenty-minute first consultation by video call is to reconstruct the map (where it burns, when, on one or two feet, what changes it) and tell you whether the right next step is a progressive loading programme, a change of footwear, or your GP with a precise request for tests.
If your picture is more "heel pain on the first steps of the morning" than burning, start here: plantar fasciitis, exercises and movements that work.
