Morton's Neuroma: Managing Forefoot Pain and Treatment Options in the UK

Morton’s neuroma is a common musculoskeletal condition affecting the forefoot, specifically the area between the third and fourth toes. Despite the name, it is not a true tumour; rather, it is a thickening (fibrosis) of the tissue surrounding one of the digital nerves leading to the toes. This occurs when the nerve is chronically compressed or irritated.

In the UK, it is most frequently seen in women, often attributed to footwear choices that compress the forefoot, such as high heels or narrow-toed shoes. However, it can affect anyone, particularly those active in high-impact sports like running or court games. Understanding the mechanics of this foot pain is the first step toward effective management and recovery.

The symptoms of Morton’s neuroma often develop gradually. Unlike a bruise or an injury, there is usually no outward sign of swelling or redness. Instead, patients typically describe internal sensations:

• Sharp or burning pain: Often felt in the ball of the foot, radiating towards the toes.
• Feeling of a 'stone in the shoe': A common description is the sensation of standing on a folded sock or a pebble that isn't actually there.
• Numbness or tingling: You may experience 'pins and needles' in the affected toes.
• Worsening with activity: The pain usually intensifies when walking or wearing tight shoes and often improves immediately upon removing the shoe and massaging the foot.

The primary cause is pressure. When the metatarsal bones (the long bones in your foot) are squeezed together, they can pinch the nerve. According to NHS clinical knowledge, several factors increase the likelihood of developing this condition:

• Footwear: High heels higher than two inches or shoes with a pointed 'toe box' force the foot into a position that compresses the digital nerves.
• High-impact sports: Activities like jogging or aerobics involve repetitive trauma to the ball of the foot.
• Foot Deformities: People with bunions, hammer toes, high arches, or flat feet (pes planus) are at a higher risk due to altered foot mechanics.
• Occupational Factors: Jobs requiring prolonged squatting or pressure on the forefoot can exacerbate nerve irritation.

Diagnosis usually begins with a physical examination by a healthcare professional. A GP or podiatrist will often perform the 'Mulder’s Click' test, which involves squeezing the forefoot to see if it elicits pain or a characteristic clicking sensation as the neuroma moves between the bones.

While the diagnosis is often clinical, NICE (National Institute for Health and Care Excellence) guidelines suggest that imaging is not always necessary for initial management. However, if the diagnosis is unclear or symptoms persist, an ultrasound scan or an MRI may be used to confirm the size and location of the neuroma and rule out other conditions like stress fractures or bursitis.

Most cases of Morton’s neuroma can be managed effectively without surgery. The goal is to reduce pressure on the nerve to allow inflammation to subside. Recommended steps include:

Footwear Modifications

Switching to shoes with a wide toe box allows the toes to spread naturally. Avoiding high heels and thin-soled shoes is crucial. Footwear with good arch support can also help redistribute weight away from the painful area.

Orthotics and Padding

Over-the-counter metatarsal pads (placed just behind the ball of the foot) can lift and separate the metatarsal bones. Custom-made orthotic insoles, prescribed by a podiatrist, may be necessary for those with specific foot shapes or gait issues.

Pain Management

Anti-inflammatory medications like ibuprofen can help manage acute pain. Applying ice packs to the ball of the foot for 10–15 minutes after activity can also reduce local swelling and discomfort.

If you have been suffering from persistent foot pain for more than two weeks despite changing your footwear, it is time to seek professional advice. You can speak to a GP online to discuss your symptoms from the comfort of your home. An online doctor can:

• Assess the history of your pain and provide a clinical opinion.
• Advise on appropriate over-the-counter medications.
• Issue a private sick note if your condition prevents you from performing work duties that involve standing or walking.
• Provide a referral letter to a private podiatrist or orthopaedic specialist for further imaging or steroid injections.

Early intervention is key to preventing the neuroma from enlarging, which makes conservative treatment more likely to succeed.

If conservative measures do not provide relief after several months, your doctor may suggest more invasive options:

• Steroid Injections: Corticosteroid injections mixed with local anaesthetic can significantly reduce inflammation and pain around the nerve.
• Sclerosant Injections: These involve injecting a solution (often alcohol-based) to intentionally deaden the nerve.
• Surgery (Neurectomy): As a last resort, a surgeon may remove the affected nerve tissue. While highly effective for pain, it results in permanent numbness in the area between the toes.
