What Is Morton’s Neuroma?

If you feel like there’s a pebble in your shoe that you can never seem to find — or you experience burning, tingling pain in the ball of your foot that shoots into your toes — Morton’s neuroma is one of the most likely explanations. We diagnose this condition regularly at Balance Foot & Ankle and want you to know there are effective treatments at every stage.

Despite its name, Morton’s neuroma isn’t a true tumor. It’s a perineural fibrosis — a thickening of the tissue surrounding the common digital nerve as it passes between two metatarsal heads. The nerve becomes entrapped by the deep transverse intermetatarsal ligament and the surrounding bony and soft tissue structures. Chronic compression causes the nerve to swell, develop fibrotic scar tissue around its sheath, and become progressively more irritable.

The condition most commonly affects the third intermetatarsal space (between the third and fourth metatarsal heads), followed by the second intermetatarsal space. The third space is predisposed because it’s where the medial and lateral plantar nerve branches converge, creating a thicker nerve that’s more susceptible to compression. Morton’s neuroma affects women approximately 8–10 times more frequently than men, largely due to footwear patterns (narrow toe boxes and high heels).

Causes and Risk Factors

Morton’s neuroma develops when the interdigital nerve is repeatedly compressed between the metatarsal heads. This compression can be caused by external factors (shoes), structural factors (foot mechanics), or both working together.

• Narrow, tight shoes: The single biggest modifiable risk factor. Shoes that squeeze the metatarsal heads together compress the nerve between them. High heels compound the problem by shifting body weight forward onto the compressed forefoot.
• High heels: Heels over 2 inches increase metatarsal head pressure by 75% compared to flat shoes and force the toes into a narrow toe box. This creates the dual compression that drives neuroma formation.
• Forefoot deformities: Bunions, hammertoes, and flat feet alter forefoot mechanics and create abnormal pressure patterns that can irritate interdigital nerves.
• High-impact activities: Running, court sports, and activities with repetitive forefoot loading increase the mechanical irritation on the nerve.
• Foot structure: A long second or third metatarsal, hypermobile first ray, or excessively flexible forefoot creates conditions where the nerve experiences more shearing force.

Symptoms of Morton’s Neuroma

Morton’s neuroma symptoms are distinctive and often described in vivid, specific terms by patients — which actually makes diagnosis easier than many foot conditions.

• “Pebble in my shoe” sensation: The most classic description. You feel a mass or foreign object under the ball of your foot that isn’t there when you check.
• Burning or sharp pain: Concentrated between the affected toes, typically between the third and fourth. The pain can be described as burning, stinging, or electric-shock-like.
• Radiation into the toes: Pain, tingling, or numbness that shoots from the ball of the foot into the adjacent toes. Some patients feel the toes going numb.
• Relief with shoe removal: Taking off the shoe and rubbing the forefoot provides immediate, significant relief — a hallmark of neuroma that distinguishes it from other forefoot conditions.
• Worse in tight shoes: Symptoms flare in narrow shoes, high heels, and during activities that compress the forefoot. Better in wide, open shoes or barefoot.
• Clicking sensation: Some patients describe a clicking or popping feeling when walking, caused by the enlarged nerve snapping between the metatarsal heads.

How We Diagnose Morton’s Neuroma

At Balance Foot & Ankle, diagnosis begins with a focused clinical examination. We perform the Mulder’s test — squeezing the forefoot laterally while applying pressure in the affected intermetatarsal space. A positive Mulder’s sign produces a palpable (and sometimes audible) click as the neuroma pops between the metatarsal heads, often accompanied by the patient’s typical pain. This test has high specificity for neuroma.

Diagnostic ultrasound is our preferred imaging modality — it visualizes the neuroma as a hypoechoic (dark) mass between the metatarsal heads in real time. Ultrasound can measure the neuroma’s size (which helps predict treatment response) and is performed in the office during the same visit. MRI provides excellent soft-tissue detail but is reserved for complex cases where multiple diagnoses are being considered. X-rays don’t show neuromas but are useful for evaluating bone structure, metatarsal length patterns, and ruling out other pathology.

Conservative Treatment

Wider Shoes with a Low Heel

Switching to shoes with a wide, round, or anatomically shaped toe box is the single most impactful first step. The toe box must be wide enough that the metatarsal heads aren’t compressed together. Aim for heels under 2 inches — every additional inch of heel height increases forefoot pressure dramatically. Athletic shoes from Altra (foot-shaped toe box), New Balance (wide widths), and HOKA (roomy plus rocker sole) are excellent choices.

Metatarsal Pads

A metatarsal pad placed just proximal (behind) to the metatarsal heads lifts and separates the metatarsals, creating more space for the nerve. This reduces compression with every step. The pad must be positioned correctly — too far forward and it increases pressure; too far back and it has no effect. We guide patients on proper placement during their office visit. Adhesive felt pads, gel pads, or pads built into orthotics all work.

Custom Orthotics

A custom orthotic with a built-in metatarsal pad provides consistent support and correct positioning in every shoe. For patients with contributing biomechanical factors (flat feet, hypermobile first ray), the orthotic addresses the structural cause while the metatarsal pad treats the nerve compression directly. Over-the-counter insoles with a metatarsal ridge are a reasonable starting point for mild cases.

Injection Therapies

Corticosteroid Injection

A cortisone injection into the affected intermetatarsal space reduces inflammation and swelling around the nerve, providing relief that typically lasts 2–6 months. We perform injections under ultrasound guidance for precise needle placement. Most patients experience significant improvement within 48–72 hours. We limit cortisone injections to 3 per year to avoid potential side effects including fat pad atrophy and plantar plate weakening.

Alcohol Sclerosing Injections

A series of 4–7 injections of dilute alcohol (4% ethanol) spaced 1–2 weeks apart chemically reduces the neuroma. The alcohol causes controlled fibrosis that shrinks the neuroma over time. Studies show 60–89% success rates, making this an excellent intermediate option between conservative care and surgery. The injections are mildly uncomfortable but tolerable, and there’s no downtime after each treatment.

Surgery for Morton’s Neuroma

When 3–6 months of conservative treatment (including injections) fails to provide adequate relief, surgical intervention is highly effective. The two main surgical approaches are neurectomy and nerve decompression.

Neurectomy (Nerve Excision)

The traditional and most common surgical approach. The affected portion of the nerve is excised (removed) through a dorsal (top of foot) or plantar (bottom of foot) incision. The dorsal approach is preferred because it avoids a weight-bearing incision, allowing earlier return to walking. Success rates exceed 80% for properly selected patients. The trade-off is permanent numbness in the adjacent sides of the two affected toes — most patients find this is a trivial side effect compared to the pain they were experiencing.

Nerve Decompression

A newer approach that releases the deep transverse intermetatarsal ligament without removing the nerve. This eliminates the source of compression while preserving nerve function (no numbness). Studies show comparable success rates to neurectomy for neuromas smaller than 5 mm. For larger neuromas, neurectomy remains more predictable. Recovery is faster than neurectomy — most patients are in regular shoes within 2–3 weeks.

Recovery from neuroma surgery: weight-bearing in a surgical shoe immediately after surgery, transition to regular shoes at 2–4 weeks, return to full activity at 4–6 weeks. Some patients experience temporary burning or tingling during nerve healing, which resolves over 2–3 months.

Frequently Asked Questions

Can Morton’s neuroma go away without treatment?

Small neuromas in the early inflammatory stage can resolve with simple footwear changes — switching to wider shoes and avoiding high heels may be enough to relieve the compression and allow the nerve inflammation to settle. However, once the nerve has developed significant perineural fibrosis (chronic thickening), the structural change is permanent. The symptoms can still be managed effectively with metatarsal pads and proper shoes, but the neuroma itself won’t disappear without intervention.

What size neuroma needs surgery?

Size alone doesn’t determine whether surgery is needed — symptoms and response to conservative treatment are the deciding factors. However, neuromas larger than 5 mm on ultrasound are less likely to respond to conservative measures alone. Very large neuromas (over 10 mm) typically require surgical excision because the fibrotic mass is too large to be adequately decompressed by pads and shoe changes. The decision is always based on your symptom severity and how well you respond to non-surgical treatment.

Can I exercise with Morton’s neuroma?

Yes, with modifications. Avoid activities that load the forefoot heavily (running, jumping, high-impact aerobics) during acute flare-ups. Swimming, cycling, and elliptical training are excellent alternatives that maintain fitness without compressing the nerve. When returning to higher-impact activities, use wide shoes with metatarsal pads and build back gradually. Many patients with well-managed neuromas continue running and playing sports with appropriate footwear.

Is numbness after neuroma surgery permanent?

After neurectomy (nerve removal), the adjacent sides of the two toes supplied by the excised nerve will have permanent numbness. For example, removing a third interspace neuroma causes numbness on the adjacent sides of the third and fourth toes. Most patients find this trade-off acceptable and report that the numbness becomes unnoticeable after a few months. Nerve decompression (releasing the ligament without removing the nerve) preserves sensation.

The Bottom Line

Morton’s neuroma is a common, treatable cause of burning forefoot pain. The majority of patients get excellent relief from the combination of wider shoes and metatarsal pads. When conservative measures aren’t enough, cortisone injections and alcohol sclerosing injections provide effective intermediate options. Surgery — either nerve decompression or neurectomy — offers definitive relief for persistent cases with success rates exceeding 80%. Don’t suffer through forefoot pain hoping it will resolve — early treatment prevents the neuroma from enlarging and gives you more options.
