Morton’s neuroma is a thickening of the tissue surrounding the digital nerve between the third and fourth metatarsals — the long bones in the middle of your foot. Despite its name, it is not a tumour. It is a benign but painful nerve condition that affects the ball of the foot and responds well to early podiatric care.
If you feel a burning or shooting pain between your toes, a tingling or numbness in the ball of your foot, or the persistent sensation of a pebble in your shoe that eases when you remove it and rub your foot, Morton’s neuroma is a likely cause. In Sydney, our podiatrists at ModPod diagnose and treat this condition regularly across our five clinics.
This guide covers what Morton’s neuroma is, how we identify it, and the full range of treatment options — from footwear changes through to surgery.
What Is Morton’s Neuroma?
Morton’s neuroma develops when the plantar digital nerve — the nerve running between your metatarsal heads — is repeatedly compressed or irritated. The protective sheath surrounding the nerve responds by thickening. Over time, this thickened tissue creates the burning pain and altered sensation that defines the condition.
It most commonly affects the nerve between the third and fourth toes, though the second and third interspace is occasionally involved. The condition is more common in women than in men, and most presentations occur in adults aged 30–60 — though we see it across a wider age range.
Morton’s neuroma is not a structural foot deformity and does not show on X-ray. It is a soft-tissue nerve condition diagnosed clinically and, when needed, confirmed by ultrasound.
Recognising the Symptoms
Morton’s neuroma produces a characteristic cluster of symptoms in the forefoot. The most common features are:
- Burning, shooting, or aching pain in the ball of the foot, typically between the third and fourth toes
- Tingling, numbness, or pins-and-needles sensation in the affected toes
- The feeling of standing on a small pebble or a fold in your sock — a sensation that eases when you remove your shoe and massage the foot
- Pain that worsens in narrow or high-heeled footwear and improves in flat, wide shoes
- Occasional sharp, electric-like pain during walking or prolonged standing
Symptoms often begin mild and intermittent — noticeable only in tight shoes — and worsen progressively if left untreated. In advanced cases, pain occurs during barefoot walking or at rest.
What Causes Morton’s Neuroma?
Morton’s neuroma develops from repeated compression or irritation of the digital nerve. Several factors drive this process:
Footwear
Narrow toe boxes squeeze the metatarsal heads together, compressing the nerve with every step. High heels shift body weight onto the forefoot, increasing pressure through the nerve space. These are the most common contributing factors and the first thing we address in clinical management.
Foot Structure
High-arched feet (pes cavus) concentrate pressure under the metatarsal heads. Flat feet cause excessive pronation — inward rolling — that stresses the forefoot with each stride. Bunions alter forefoot mechanics in ways that can increase nerve compression over time.
Activity and Load
Repetitive forefoot loading is a significant driver. Running, especially on hard surfaces, generates sustained impact through the metatarsal region. Cyclists in tight-fitting shoes, rock climbers, and people whose work requires prolonged standing are also at elevated risk.
Other Contributing Factors
Trauma to the forefoot, inflammatory arthritis, and hypermobile joints can all irritate the digital nerve. In many cases, Morton’s neuroma develops from cumulative load rather than a single identifiable event.
How Is Morton’s Neuroma Diagnosed?
Diagnosis begins with a detailed clinical assessment. Your podiatrist will take a thorough history — the location, character, and timing of your pain — before performing a physical examination.
Mulder’s Click Test
This is the principal clinical test for Morton’s neuroma. Your podiatrist compresses the metatarsal heads from the sides while pressing upward on the affected interspace between the toes. A palpable click combined with reproduction of your familiar symptoms is a positive result. When performed correctly, Mulder’s click test is both sensitive and specific for Morton’s neuroma.
Ultrasound Assessment
When the clinical picture is unclear, or to confirm the size and precise location of the neuroma before planning treatment, we refer for diagnostic ultrasound. Ultrasound is the preferred imaging modality — it visualises soft tissue well, is non-invasive, and allows the nerve to be assessed dynamically in real time. MRI is occasionally used when ultrasound findings are equivocal, but this is less common in routine clinical practice.
Conservative Treatment for Morton’s Neuroma
The majority of Morton’s neuroma cases respond to conservative, non-surgical management. At ModPod Podiatry, we approach treatment systematically, starting with the simplest and least invasive interventions.
Footwear Modification
Switching to shoes with a wide toe box and a low heel is frequently the most effective early step. It removes the compression driving the condition and gives the nerve space to decompress between loading cycles. Many patients with mild or moderate neuroma achieve meaningful improvement through footwear changes alone.
Metatarsal Padding
A small domed metatarsal pad, placed just behind the metatarsal heads, spreads the bones apart and offloads the compressed nerve. Fitted precisely by a podiatrist, this can reduce pain within days. Placement matters — a pad positioned incorrectly can worsen symptoms rather than relieve them.
Custom Orthotics
Custom orthotics address the underlying biomechanical factors contributing to nerve compression. A prescription orthotic with integrated metatarsal support redistributes plantar pressure more evenly across the forefoot, reducing the load through the affected nerve space. For patients with flat feet, high arches, or abnormal gait patterns, orthotics are a core component of long-term management.
Activity Modification
Reducing high-impact activities — particularly running on hard surfaces — during the initial treatment phase allows inflammation around the nerve to settle. We develop a graduated return-to-activity plan once symptoms stabilise, so patients can get back to sport without re-aggravating the nerve.
Anti-Inflammatory Measures
Applying ice to the forefoot for 15–20 minutes after activity reduces local inflammation. Non-steroidal anti-inflammatory medication may be appropriate in the short term — discuss this with your GP before use, particularly if you have any contraindications.
When Conservative Treatment Is Not Enough
When symptoms persist despite three to six months of consistent conservative management, additional options are available.
Ultrasound-Guided Cortisone Injection
A cortisone injection into the affected nerve interspace, guided by ultrasound imaging, delivers a concentrated anti-inflammatory agent directly to the site of compression. This is performed by a GP or specialist under imaging guidance. Results vary — some patients achieve months of meaningful relief; others see limited benefit. We coordinate referrals when this step is clinically appropriate.
Alcohol Sclerosing Injections
A series of injections using dilute alcohol solution progressively shrinks the neuroma. The evidence supports this approach as an intermediate option before surgery in persistent cases. Multiple sessions are typically required, spaced a week apart.
Surgical Excision
When all conservative and injection-based measures have failed, surgical removal of the neuroma is an option. Surgery is effective, though it carries a small risk of permanent numbness in the affected toes and requires several weeks of recovery. We refer to an orthopaedic foot and ankle surgeon when surgery is being considered.
Why Early Treatment Matters
The longer Morton’s neuroma goes untreated, the more the nerve tissue thickens — and the harder it becomes to resolve with conservative management. A neuroma treated early, when symptoms are mild and occur only in tight shoes, often responds well to footwear modification and metatarsal padding alone. A neuroma that has been present for years is significantly more difficult to treat without injection or surgical intervention.
If you have forefoot pain that fits the description above, early assessment is the right call.
Morton’s Neuroma in Sydney
Sydney’s lifestyle contributes to Morton’s neuroma risk. Hard-surface running — along coastal paths, in inner-city parks, on footpaths — is a staple of Sydney’s running culture and generates substantial repetitive forefoot impact. We see a significant proportion of Morton’s neuroma presentations in runners training for events such as the City2Surf. Running in worn footwear, or in minimalist shoes without adequate forefoot cushioning, amplifies this risk considerably.
Under the Medicare EPC (Enhanced Primary Care) scheme, patients with a chronic condition managed by their GP — including chronic musculoskeletal conditions — may be eligible for a Medicare rebate on up to five allied health visits per calendar year. Your GP writes an EPC care plan and includes podiatry in the Team Care Arrangement. Each podiatry visit then attracts a Medicare rebate (currently approximately $58). If you have private health insurance with Extras cover, podiatry consultations are typically rebatable through Medibank, BUPA, HCF, NIB, and most other major funds.
ModPod Podiatry has five Sydney clinics: CBD, Mosman, Dee Why, Rose Bay, and North Ryde. All five clinics are equipped for biomechanical assessment, orthotic prescription, and the clinical management of Morton’s neuroma.
Frequently Asked Questions
Q: What does Morton’s neuroma feel like?
A: The hallmark description is a burning or shooting pain between the third and fourth toes, with tingling or numbness in the affected toes. Most people also describe the sensation of standing on a small pebble or a fold in their sock — a sensation that reliably eases when they remove their shoe and rub the foot.
Q: Can Morton’s neuroma go away on its own?
A: Mild, early-stage Morton’s neuroma can improve with simple footwear changes and activity modification. Without addressing the underlying mechanical cause, however, symptoms typically return and progress over time. Professional assessment and treatment give you the best chance of resolving the condition durably.
Q: Do orthotics help Morton’s neuroma?
A: Yes — particularly when abnormal foot mechanics are contributing to the nerve compression. Custom orthotics with metatarsal support redistribute forefoot pressure and reduce the load through the affected nerve space. They are most effective when combined with appropriate footwear changes.
Q: How is Morton’s neuroma diagnosed?
A: Primarily through clinical examination, including Mulder’s click test. Your podiatrist compresses the metatarsal heads laterally while pressing upward on the interspace — a palpable click with reproduction of your symptoms confirms the diagnosis. Ultrasound imaging is used to confirm size and location when the clinical picture is unclear.
Q: What is the best treatment for Morton’s neuroma?
A: There is no single best treatment — the right approach depends on symptom severity, duration, and your foot mechanics. For most patients, a combination of footwear modification, metatarsal padding, and custom orthotics produces a good outcome. Cortisone injection and surgery are reserved for cases that do not respond to conservative management over several months.
