Also called: Morton neuroma; interdigital neuroma

Relief and prevention Stretch Massage Strength

Burning, tingling or a sensation of a pebble under the ball of the foot, usually between the third and fourth toes. A nerve has thickened where it is squeezed between the metatarsal heads - and narrow shoes are the main squeeze.

How common: Symptomatic in roughly 1-2% of adults; far more common in women

What it is

A Morton's neuroma is thickening and fibrosis around a nerve running between the metatarsal bones, most often between the third and fourth toes. It is not a tumour despite the name - it is a compressive change in the nerve's surrounding tissue.

The distinguishing feature is the character of the symptoms. Ordinary forefoot overload produces aching and tenderness; this produces burning, tingling, numbness and a sensation of walking on a fold in the sock or a pebble, and it is often relieved dramatically by taking the shoe off and rubbing the foot.

What it feels like

  • Burning or shooting pain into the third and fourth toes
  • A sensation of a pebble or a folded sock under the ball of the foot
  • Numbness or tingling in the adjacent sides of two toes
  • Relieved by removing the shoe and massaging the foot
  • Sometimes a click felt when squeezing the forefoot from the sides

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 between the metatarsal heads
The nerve runs in a narrow space between the metatarsal bones. Anything that squeezes them together compresses it, producing the thickening and fibrosis that make the symptoms permanent.
Narrow toe boxes
The main squeeze. Shoes narrower than the foot press the metatarsal heads together for hours a day, and it is by far the most modifiable factor.
High heels
Load is transferred forward onto the forefoot and the toes are pushed into the narrow front of the shoe. The combination is why this condition is far more common in women.
The anatomy of the third space
The nerve in the third space is formed by branches from two nerves and is relatively fixed in position, making it more vulnerable to compression. This is why the third-fourth toe space is the usual site.
Excessive forefoot loading
Tight calves, a stiff big toe and a high arch all shift more load onto the forefoot, increasing the pressure through the metatarsal heads.
Prolonged standing and walking
Occupational standing on hard surfaces increases the cumulative compression time considerably.
Foot shape
A splayed forefoot, bunions, or a hypermobile foot allow more movement between the metatarsal heads, increasing the irritation of the nerve between them.
Running
Repeated forefoot loading with each stride, particularly in narrow running shoes, is a common setting for it to develop.
Being mistaken for metatarsalgia
General forefoot overload and a neuroma are treated differently. The burning, tingling and numbness distinguish them and are worth reporting specifically.

Who tends to get it

  • Women, in whom it is several times more common
  • Regular wearers of narrow or heeled shoes
  • Runners, particularly in narrow shoes
  • Anyone with bunions, splayed forefeet or tight calves
  • People who stand all day on hard floors

What makes it worse, and what settles it

Makes it worse

  • Narrow toe boxes and heels, which are the mechanism
  • Prolonged standing and walking in the aggravating shoes
  • High-impact activity on the forefoot
  • Squeezing the forefoot, which is what the shoe is doing all day
  • Ignoring it, since the nerve fibrosis becomes permanent

Settles it

  • Wide toe box, low-heeled shoes - the change that matters most
  • A metatarsal pad placed just behind the affected space to spread the metatarsal heads
  • Calf stretching and foot intrinsic strengthening to reduce forefoot loading
  • Toe spacers to widen the forefoot
  • Corticosteroid injection or other interventions where conservative measures fail

What actually helps

The short version: Perineural fibrosis of an interdigital nerve, usually between the third and fourth toes, compressed by narrow shoes

Strength work: Feet, Toes, Ankles; Toe Neuromuscular Exercises; intrinsic foot work; Feet, Toes, Ankles: Intrinsic Foot Muscles

Stretching: Feet, Toes, Ankles; toe splaying

Massage: Feet, Toes, Ankles; Massage Ball - avoid direct pressure on the neuroma itself

Also worth doing: Wide toe-box shoes; metatarsal pad; Wear Toe Spacers

What the evidence says: Footwear change and metatarsal padding do most of the work. Foot strengthening and spacers help. Do not press directly on the neuroma.

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; burning in both feet suggests neuropathy instead

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

Footwear change plus a correctly placed metatarsal pad relieves symptoms in a large proportion of people, often within weeks. Injection helps many of those who do not respond, and surgical removal of the nerve is effective for persistent cases at the cost of permanent numbness between the toes. The fibrosis around the nerve does not reverse, so the goal is removing the compression rather than undoing the change.

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.
