Morton’s neuroma is a painful forefoot condition involving irritation and thickening of a nerve between the toes, most commonly between the third and fourth metatarsal bones. Despite the name, it is not a true tumour. Instead, it represents a compression-related nerve injury where repeated pressure and shear forces cause the nerve to become swollen and sensitive.
The condition affects the common plantar digital nerve, which runs between the metatarsal heads before splitting to supply sensation to the toes. When this nerve is repeatedly compressed, often by tight footwear, altered foot mechanics, or excessive forefoot loading, it can become painful and hypersensitive. People often describe Morton’s neuroma as feeling like they are walking on a pebble, marble, or folded sock.
Morton’s neuroma is more common in adults and frequently affects people who spend long periods on their feet. Physiotherapy for Morton’s neuroma plays an important role in reducing nerve compression, addressing contributing biomechanical factors, and guiding a safe return to walking, work, and sport.
Key Facts
- Morton’s neuroma most commonly affects the third intermetatarsal space, accounting for the majority of cases, due to increased nerve mobility and compression in this region. 🔗
- The condition is more frequently reported in women than men, which is thought to be related in part to footwear choices that increase forefoot compression. 🔗
- Conservative management, including physiotherapy and footwear modification, is widely recommended as first-line treatment before considering injections or surgery. 🔗
Risk Factors
- Use of tight, narrow, or high-heeled footwear.
- Occupations requiring prolonged standing or walking.
- Foot structure that increases forefoot pressure, such as a long second or third metatarsal.
- High-impact sports involving running and jumping.
- Previous forefoot injury or surgery.
Symptoms
- Burning or sharp pain in the ball of the foot, often radiating into the toes.
- A sensation of walking on a pebble, marble, or folded sock.
- Tingling, numbness, or pins-and-needles in the affected toes.
- Pain that worsens with tight shoes or high heels.
- Relief when shoes are removed or the foot is massaged.
Aggravating Factors
- Wearing narrow or tight footwear that compresses the forefoot.
- Prolonged walking or standing, particularly on hard surfaces.
- Running or jumping activities that increase forefoot loading.
- High-heeled shoes that shift body weight onto the ball of the foot.
Causes
Morton’s neuroma develops when the common plantar digital nerve is repeatedly compressed between the metatarsal heads. This compression is often worsened by footwear that narrows the forefoot or elevates the heel, increasing pressure through the ball of the foot.
Foot biomechanics also play a key role. Excessive forefoot loading, reduced shock absorption, or instability of the metatarsals can increase shear forces on the nerve. Over time, the nerve responds by thickening and becoming hypersensitive, leading to the characteristic pain and altered sensation. Physiotherapists assess these contributing factors to determine why the nerve has become irritated and how to reduce ongoing compression.
How Is It Diagnosed?
Diagnosis of Morton’s neuroma is primarily clinical and is based on symptom history and physical examination. A physiotherapist will ask about footwear, activity levels, and the exact location and nature of the pain. Examination often includes palpation of the intermetatarsal spaces and assessment of forefoot loading during walking.
Reproduction of symptoms when compressing the forefoot or applying pressure between the metatarsal heads supports the diagnosis. Because symptoms can overlap with other causes of forefoot pain, imaging may be recommended if the diagnosis is uncertain or symptoms persist.
Investigations & Imaging
- Ultrasound
- Can identify thickening of the interdigital nerve and is commonly used to confirm the presence of a neuroma.
- MRI
- Provides detailed soft tissue imaging and may be used if symptoms persist or alternative diagnoses are suspected.
Physiotherapy Management
Physiotherapy for Morton’s neuroma focuses on reducing pressure on the affected nerve, improving foot mechanics, and managing pain so daily activities and sport can be resumed comfortably. Treatment is individualised based on footwear habits, activity demands, and how symptoms are provoked.
Exercise
Morton’s neuroma physiotherapy exercises aim to improve load distribution through the forefoot and reduce nerve irritation. Exercises may include intrinsic foot muscle strengthening, calf flexibility work to reduce forefoot overload, and controlled balance exercises to improve foot stability during walking and running.
Rather than aggressively stretching the forefoot, exercises are chosen to improve how force is absorbed and transferred through the foot, reducing repeated compression of the nerve between the metatarsals.
Activity Modification
Activity modification is often required in the early stages of Morton’s neuroma rehab. A physiotherapist may recommend temporarily reducing high-impact activities, limiting long periods of standing, or breaking up walking tasks to allow symptoms to settle while maintaining general fitness.
Manual Therapy
Manual therapy may be used to address contributing stiffness in the ankle, midfoot, or toes that alters forefoot loading. Soft tissue techniques may also be applied to surrounding structures to reduce local tension and improve comfort during rehabilitation.
Bracing & Taping
Taping techniques can help reduce forefoot compression by encouraging better spacing between the metatarsal heads. In Morton’s neuroma, taping is often used to offload the affected intermetatarsal space during walking and work activities.
Heat & Ice
Ice may be used after activities that aggravate symptoms to help settle local pain and irritation around the nerve. Heat is generally less useful for Morton’s neuroma and is not commonly recommended.
Tens
TENS can be used as part of pain management for Morton’s neuroma, particularly when nerve pain limits activity progression. It is typically used alongside, rather than instead of, active rehabilitation.
Education
Education is a key component of physiotherapy for Morton’s neuroma. This includes guidance on footwear selection, pacing of activities, symptom monitoring, and strategies to avoid prolonged nerve compression. Understanding what aggravates symptoms empowers people to manage flare-ups effectively.
Other
Other physiotherapy management may include footwear advice, referral for appropriate orthotic review if required, and a structured return-to-running or work program once symptoms are controlled.
Other Treatments
Other treatments may include corticosteroid injections to reduce nerve inflammation or alcohol sclerosing injections in selected cases. These treatments are often used alongside physiotherapy rather than as standalone solutions.
Surgery
Surgery for Morton’s neuroma is considered only when conservative treatments fail to provide relief. Surgical options typically involve removal of the affected nerve segment. While surgery can reduce pain, it also results in permanent numbness in the supplied toes, which is why non-surgical management is prioritised first.
Prognosis & Return to Activity
With early and appropriate management, the prognosis for Morton’s neuroma is generally good. Many people experience significant symptom improvement with footwear changes, activity modification, and physiotherapy. Persistent symptoms may require longer-term management or escalation to other treatments.
Complications
- Chronic forefoot pain limiting walking tolerance.
- Reduced participation in work or recreational activities.
- Persistent nerve sensitivity despite treatment.
Preventing Recurrence
- Choose footwear with adequate width across the forefoot to reduce nerve compression.
- Avoid prolonged use of high heels or narrow shoes that increase forefoot pressure.
- Maintain calf and foot strength to improve shock absorption during walking and running.
- Gradually increase activity levels to avoid sudden spikes in forefoot load.
When to See a Physio
- If you have ongoing forefoot pain that does not improve with footwear changes.
- If tingling or numbness develops in the toes.
- If pain is limiting your ability to work, exercise, or walk comfortably.
