A Comprehensive Guide to Morton’s Neuroma

Neuroma, particularly Morton’s neuroma, is a painful condition caused by nerve thickening in the foot. This guide by Manly Cove Podiatry provides a detailed overview of its causes, symptoms, and treatment options, equipping you with the knowledge to manage and prevent this common foot ailment effectively. 

What is a Neuroma?

A neuroma, commonly referred to as Morton’s neuroma, is a painful condition characterised by the thickening of nerve tissue. This typically occurs between the toes, most often between the third and fourth toes, and results from compression and irritation of the nerve. The thickening is the body’s response to the irritation or injury.

  • Nature of Neuroma: Unlike what the term might suggest, a neuroma is not a true tumour but rather a fibrous tissue formation around the nerve.
  • Common Locations: While it can occur in various parts of the foot, it most frequently affects the area between the toes, impacting nerve function and causing pain.
  • Risk Factors: Factors contributing to its development include wearing high heels or tight shoes, certain foot deformities such as high arches or flat feet, and repetitive stress from sports.

Causes of Neuroma in the Foot

Understanding the causes of neuroma is essential for prevention and effective treatment. Several factors can contribute to the development of this condition, both anatomical and lifestyle-related.

  • Biomechanical Imbalances: Abnormalities in foot mechanics, such as overpronation (excessive inward foot rolling) or high arches, can lead to nerve compression.
  • Footwear Choices: Tight footwear and high heels can put extra pressure on the toes and forefoot, leading to nerve compression.
  • Repetitive Stress: Activities that involve repetitive pressure on the foot, like running or court sports, can exacerbate the risk of developing a neuroma.
  • Previous Foot Injuries: Past injuries to the foot may increase the likelihood of neuroma as the nerve tries to heal in a scarred or altered environment.

Identifying Symptoms of Neuroma

Recognising the symptoms of a neuroma early can significantly improve the outcome of treatments. The symptoms can vary in intensity and may worsen over time if not addressed.

  • Pain and Discomfort: Initially, the pain might feel like a burning sensation in the ball of the foot that may radiate to the toes.
  • Numbness and Tingling: As the condition progresses, it might lead to numbness or a tingling sensation in the toes, often described as feeling like there is a pebble in the shoe.
  • Worsening with Activity: Symptoms are typically exacerbated by activities that involve significant pressure on the forefoot, such as walking or running, and may improve with rest.

Diagnostic Approaches for Neuroma

Diagnosing a neuroma involves a combination of clinical examination and imaging studies to accurately identify the condition and rule out other causes of foot pain.

  • Clinical Examination: A podiatrist will perform a physical examination of the foot to check for signs of neuroma, such as a palpable mass or a “click” felt when pressing together the sides of the foot (Mulder’s sign).
  • Imaging Tests: While X-rays cannot show soft tissues like neuromas, they can help exclude other causes such as fractures or arthritis. Ultrasound and MRI are more effective in visualising the thickened nerve.
  • Weight-Bearing Tests: Assessments while standing or during walking can help identify changes in the foot structure and dynamics that contribute to neuroma formation.

Treatment Options Available for Neuroma

Treatment for neuroma typically starts with conservative approaches and progresses to more invasive methods if necessary. The goal is to relieve pressure on the nerve and alleviate pain.

  • Shoe Modifications: Switching to shoes with a wider toe box and lower heels can significantly reduce pressure on the neuroma.
  • Orthotic Devices: Custom orthotic devices designed by a podiatrist can help correct foot biomechanics and redistribute pressure away from the neuroma.
  • Medications: Anti-inflammatory medications or corticosteroid injections may be used to reduce swelling and pain in the affected area.
  • Physical Therapy: Techniques such as ice massage, ultrasound therapy, and stretches can help relieve symptoms and improve foot function.

Importance of Footwear in Managing Neuroma

Choosing the right footwear is crucial in both treating and preventing neuroma, as improper shoes can increase the risk of nerve compression.

  • Proper Fit and Style: Shoes should provide enough room for the toes to move freely and should not compress the front of the foot. Low-heeled shoes are preferable.
  • Supportive Features: Shoes with adequate arch support and cushioning can help absorb impact and distribute pressure evenly across the foot.
  • Consultation for Footwear: A podiatrist can provide guidance on the best types of shoes for your specific foot shape and condition, and if necessary, recommend custom shoes or modifications.

Custom Orthotics and Their Role in Neuroma Treatment

Custom orthotics play a significant role in treating neuroma by addressing the specific biomechanical issues that contribute to nerve compression.

  • Personalised Support: Orthotics are custom-designed inserts that fit into the shoes to provide support exactly where it’s needed, aligning the foot and reducing pressure on the affected nerve.
  • Correcting Foot Mechanics: By correcting abnormal foot mechanics such as overpronation or high arches, orthotics can relieve the direct pressure on the neuroma, mitigating pain and preventing further damage.
  • Long-term Relief: Regular use of custom orthotics can offer sustained relief from symptoms and serve as a preventive measure against the recurrence of neuroma.

Lifestyle Modifications for Neuroma Management

Adapting one’s lifestyle can significantly enhance the effectiveness of medical treatments for neuroma and help manage the symptoms more effectively.

  • Activity Adjustments: Reducing or modifying activities that exacerbate the neuroma, such as running or ballet, can help alleviate symptoms. Incorporating lower-impact exercises can maintain fitness without stressing the feet.
  • Weight Management: Maintaining a healthy weight can reduce the stress on the feet, decreasing the pressure on the neuroma and lessening pain.
  • Proper Foot Care: Regular foot care, including massages and baths, can improve circulation and reduce the symptoms associated with neuroma. Avoiding walking barefoot on hard surfaces can also prevent aggravation of the condition.

Advanced Podiatric Interventions for Neuroma

When conservative treatments are not sufficient, more advanced interventions may be necessary to alleviate the symptoms or remove the neuroma.

  • Corticosteroid Injections: These are used to provide temporary relief from pain and inflammation by directly targeting the affected area.
  • Alcohol Sclerosing Injections: A series of alcohol injections can help decrease the size of the neuroma and reduce pain by hardening the nerve tissue.
  • Surgical Options: In cases where other treatments fail, surgical intervention may be considered. This can involve removing the neuroma or releasing nearby structures to relieve pressure on the nerve.
