Burning sole of the foot

Also called: Tarsal tunnel syndrome

Relief and prevention Stretch Massage Strength

Burning, tingling or numbness in the sole of the foot, worse at night and after standing. The tibial nerve is compressed behind the inner ankle - the foot's version of carpal tunnel - and a collapsing arch increases the pull on it.

How common: Uncommon but consistently under-recognized; often mistaken for plantar fasciitis

What it is

The tibial nerve passes behind the inner ankle bone through a fibrous tunnel and divides to supply the sole. Compression there produces burning, tingling and numbness in the sole - the foot equivalent of carpal tunnel syndrome, and considerably less well recognised.

Unlike the wrist, there is often an identifiable cause: a space-occupying lesion such as a ganglion or a varicose vein within the tunnel, or a foot that pronates excessively and puts the nerve under traction with every step. Finding which is the case changes the treatment substantially.

What it feels like

Burning, tingling or numbness in the sole of the foot and the toes
Worse at night and after prolonged standing or walking
Sometimes shooting pains into the sole or up the inside of the ankle
Tapping behind the inner ankle bone reproducing the tingling
Not the sharp first-step heel pain of plantar fasciitis, which is the main alternative

What causes it

Most people have more than one of these at once, and they feed each other. Read the list looking for the two or three that sound like your week rather than for the one true answer — the ones that describe you are the ones worth acting on.

Compression in the tarsal tunnel: The nerve passes through a fibrous tunnel behind the inner ankle. Anything reducing the space or increasing pressure within it compresses the nerve directly.
A space-occupying lesion: A ganglion, a varicose vein, an accessory muscle or a bony spur within the tunnel is identifiable in a meaningful proportion of cases - more often than in carpal tunnel syndrome, which is why imaging is more useful here.
Excessive pronation and a collapsing arch: A foot that rolls in stretches the nerve around the inner ankle with every step. Traction rather than direct compression is the mechanism, and it responds to arch support and strengthening.
Previous ankle injury: A fracture or severe sprain can produce scarring or bony change within the tunnel, sometimes years before symptoms appear.
Systemic conditions: Diabetes, inflammatory arthritis and hypothyroidism all raise nerve vulnerability or produce swelling within the tunnel.
Swelling and fluid retention: Pregnancy, heart failure and venous insufficiency all increase fluid in the tissues and can compress the nerve.
Prolonged standing: Occupational standing increases venous congestion in the leg and pressure in the tunnel, which is why symptoms are worst at the end of the day.
Tight or restrictive footwear: Boots and shoes pressing over the inner ankle can compress the tunnel directly.
Being misdiagnosed as plantar fasciitis: The commonest reason it persists. The symptoms differ - burning and tingling rather than sharp first-step pain - and the treatments are entirely different.

Who tends to get it

Anyone with a flat or collapsing arch
People with diabetes or inflammatory arthritis
Anyone with a previous significant ankle injury
People who stand all day
Anyone with foot pain that burns and tingles rather than aches

What makes it worse, and what settles it

Makes it worse

Prolonged standing and walking
Excessive pronation left unsupported
Tight boots or footwear pressing over the inner ankle
Being treated as plantar fasciitis, which delays the right approach
Ignoring progressive numbness, which indicates ongoing nerve damage

Settles it

Arch support or an orthotic to reduce the traction on the nerve
Foot intrinsic and tibialis posterior strengthening to control the arch actively
Nerve gliding exercises for the tibial nerve
Calf stretching and soft tissue work around the inner ankle
Getting imaging where symptoms persist, since a treatable space-occupying cause is relatively common here

What actually helps

The short version: Tibial nerve compressed behind the inner ankle, often with a collapsing arch increasing the traction on it

Strength work: Legs: Calves: Tibialis Posterior; Feet, Toes, Ankles - support the arch to reduce nerve traction; Feet, Toes, Ankles: Intrinsic Foot Muscles

Stretching: Legs: Calves; Feet, Toes, Ankles

Massage: Feet, Toes, Ankles - avoid direct pressure over the tunnel

Also worth doing: Arch support; tibial nerve glides; night pain is characteristic

What the evidence says: Arch support to reduce nerve traction plus nerve gliding. Frequently misdiagnosed as plantar fasciitis for years - the distinguishing feature is burning and night pain.

Ready-made routineFoot & Heel Relief

qFIT already has this one built. It runs massage first, then stretching, then strength — the order that works on a body that is already sore — and every activity in it carries the reason it is there.

The button below opens your Checklist with this routine already selected, so instead of your whole list you land on just its Categories, Targets and Exercises, each with its checkbox, ready to tick as you work through them.

Get it checked if…

Progressive numbness or weakness, or burning in both feet, suggests peripheral neuropathy rather than entrapment

And whatever the body part: chest pain or unusual breathlessness on exertion; a fever alongside the pain; unexplained weight loss; pain that is constant and unrelated to how you move; new numbness, weakness or loss of bladder or bowel control; or one calf that is swollen, warm and painful. Any of those, stop and get assessed.

How it usually goes

Where excessive pronation is the driver, arch support and strengthening improve symptoms over six to twelve weeks. Where a space-occupying lesion is present, removing it is usually curative, which makes imaging worthwhile in persistent cases. Long-standing compression produces permanent numbness, so persistent or progressive symptoms deserve prompt assessment rather than another course of plantar fascia treatment.

Prevalence basis: Foot and ankle series

Others the same routine covers

These share the Foot & Heel Relief routine, so the work is the same. If one of them also sounds like you, that is a reason to expect more from it, not less.

This is general information, not a diagnosis, and it cannot examine you. If it matches you, use it to ask better questions of a clinician rather than to replace one.
