The Burning Pain Between the Toes

What Is Morton's Neuroma?

Morton's neuroma is not a true tumor but a benign thickening of the tissue surrounding a nerve that runs between the metatarsal bones, most often in the space between the third and fourth toes. Repeated compression and irritation of that nerve, usually where it passes beneath the ligament connecting the metatarsal heads, causes the surrounding tissue to thicken, which irritates the nerve further and produces the burning or electric sensation felt in the ball of the foot and toes.

The name is something of a historical accident. Thomas Morton described the condition in the 1870s, and the term stuck even though the third-and-fourth-toe web space, not the interspace he originally described, is by far the more commonly affected one.

What Does It Feel Like?

The hallmark symptom is a burning, tingling, or electric sensation concentrated in the ball of the foot and radiating into the third and fourth toes, often described as feeling like a fold in a sock or standing on a small stone that isn't actually there. Numbness in the affected toes is common, and symptoms typically worsen in tight or narrow shoes and with walking, then ease once the shoe comes off and the forefoot is rubbed or squeezed from side to side.

Some people notice they can reproduce the sensation themselves by pinching the forefoot between thumb and fingers, or by wearing a snug shoe for a while, which is one reason clinicians ask detailed questions about exactly what brings the symptoms on.

What Causes It?

Morton's neuroma develops from repeated mechanical irritation of the nerve rather than from a single injury, which places it in the same broad category as other overuse musculoskeletal conditions that build up gradually instead of announcing themselves all at once 1Ref 1National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) (2023).Sports Injuries.Frames Morton's neuroma as an overuse musculoskeletal condition that builds gradually from repeated irritation rather than a single injury.. Narrow or tight-toed shoes, high heels that push the toes forward into a shoe's narrow front, and high-impact activities that repeatedly load the forefoot are the most consistently reported contributors.

Foot shape plays a role too: a foot that pronates more than average, or one with a bunion or hammertoe altering how weight moves across the forefoot, can raise pressure on the nerve over time. It is substantially more common in women, which is generally attributed to footwear patterns rather than an anatomical difference in the nerve itself.

Neuroma vs. Metatarsalgia vs. a Stress Fracture

Sorting out neuroma vs metatarsalgia matters, because the two forefoot conditions calling attention to the same patch of skin need different first steps. Morton's neuroma causes a burning, electric, or numb sensation concentrated between two toes, driven by nerve irritation; metatarsalgia causes a duller, bruise-like ache spread more broadly under the metatarsal heads, driven by forefoot overload rather than nerve irritation; and a stress fracture causes sharp pain localized to one specific bone that tends to worsen with impact and can persist at rest.

This ball-of-foot pain pattern is also distinct from plantar fasciitis, which centers on the heel rather than the forefoot and is classically worst with the first steps out of bed in the morning 2Ref 2American Academy of Orthopaedic Surgeons (OrthoInfo) (2024).Plantar Fasciitis and Bone Spurs.Distinguishes Morton's neuroma's ball-of-foot location from plantar fasciitis, which centers on the heel and is classically worst with the first steps of the morning.. Because the three forefoot conditions can overlap, especially early on, a clinician's exam — checking for a palpable click between the metatarsal heads, or numbness in a specific toe web space — adds information a symptom description alone can't.

What Helps

Conservative treatment is the reasonable starting point for most Morton's neuroma, and a meaningful share of cases improve without any procedure. Switching to a wider shoe with a roomy toe box and a low heel immediately reduces compression on the nerve, and a metatarsal pad placed just behind the affected web space can spread the metatarsal heads apart and take pressure off the irritated nerve.

• Footwear: a wide toe box and low heel reduce compression on the nerve right away.
• Padding: a metatarsal pad shifts pressure away from the nerve rather than onto it.
• Activity changes: temporarily reducing high-impact activity lets the irritated tissue settle.
• Injections: some clinicians offer a corticosteroid injection when pain doesn't respond to footwear and padding changes alone, though relief can be temporary.

Most Morton's neuroma responds to these conservative steps, and surgery is reserved for cases that don't improve after a genuine trial of them. When footwear, padding, and activity changes aren't enough, the next decision is usually between an injection and surgery for the nerve between your toes, a choice worth understanding in detail, since morton's neuroma treatment options carry different trade-offs in relief and recovery time.

Do You Need Imaging, and When to See a Clinician

Morton's neuroma is usually diagnosed from the history and a physical exam rather than imaging, since a clinician can often reproduce the burning sensation by compressing the forefoot or feel a palpable click between the metatarsal heads. Ultrasound or MRI is sometimes used when the diagnosis is unclear or when planning an injection or procedure, because a neuroma is a soft-tissue finding that a standard X-ray will not show.

It's worth arranging an evaluation sooner if the numbness is constant rather than intermittent, if pain persists despite several weeks of footwear and padding changes, or if symptoms are severe enough to change how someone walks, since a clinician can rule out a stress fracture or nerve entrapment elsewhere and tailor treatment accordingly.
