Morton's Neuroma

That burning pain under the front of your foot makes you wince with every step. It feels like you're walking on a bump or a crease in your sock. Electric shocks radiate to your toes. As physical therapists specializing in biomechanical foot assessment, we regularly see patients who are concerned about these symptoms.

Good news: 80% of cases respond to conservative treatment without surgery.¹ The key is to act quickly.

What science shows: - Morton's neuroma is not a tumor, it is a thickening of the tissue around a nerve - Treatment works best before the 4th month of symptoms - Exercises and shoe modifications significantly relieve pain - Physical therapy combines nerve mobilization, strengthening, and education

This guide explores the causes, symptoms, and effective treatments. To understand physical therapy in general, check out our comprehensive guide.

What is Morton's neuroma?

Morton's neuroma is a thickening of the tissue surrounding an interdigital nerve (nerve between the toes). It is usually located between the third and fourth toes. Despite its name, it is not a tumor. It is an irritation or compression that causes painful inflammation.

The interdigital nerve transmits sensory information to your toes. It also controls the muscles in your foot. It is like an electrical wire that carries information.

When this nerve undergoes repeated compression, the tissue thickens to protect itself. This process creates the characteristic bump known as a neuroma.

In 80% of cases, the neuroma forms between the third and fourth metatarsals (long bones of the foot). It can also appear between the second and third metatarsals, but this is less common.

Morton's neuroma is one of the most common types of foot pain. If you have other foot pain, check out our guide to joint pain to better understand your condition.

What are the causes of Morton's neuroma?

A neuroma develops when the interdigital nerve is subjected to pressure or repeated microtrauma. The main causes are tight shoes, high heels, and mechanical overload of the forefoot.

Women between the ages of 40 and 60 are most affected. This may be due to frequently wearing narrow shoes. Shortened calf muscles also increase the load on the metatarsals.

If you have tight calves, Achilles tendonitis may be a related condition to watch out for. A shortened calf alters the biomechanics of the foot and increases pressure on the forefoot.

Runners and athletes who participate in sports involving repeated impact are particularly at risk. Tibial periostitis is another common condition among runners who share certain biomechanical risk factors.

Foot deformities such as hammer toes can also contribute to changes in pressure distribution under the forefoot and increase the risk of neuroma. A comprehensive biomechanical assessment will identify these contributing factors.

What are the symptoms of Morton's neuroma?

Symptoms include burning pain under the forefoot, electric shocks, and numbness in the adjacent toes. The pain is typically located between the third and fourth toes.

If you recognize these symptoms, seek medical advice to prevent the condition from worsening.

It is important to distinguish Morton's neuroma from other types of pain in the forefoot. Metatarsalgia also causes pain under the metatarsals, but it is generally more diffuse and mechanical. Plantar fasciitis causes pain under the heel that improves after a few steps. Tarsal tunnel syndrome causes similar nerve symptoms, but on the inside of the foot and the sole.

If you also have a deformity of the big toe, check out our article onhallux valgus to understand how foot deformities can contribute to overloading the forefoot.

How is Morton's neuroma diagnosed?

The diagnosis is based on the history of symptoms and clinical examination. Imaging is rarely necessary, except to rule out other causes.

During the examination, the physical therapist will: - Take a history of your symptoms - Examine the mobility of your joints - Assess the gliding of your nerves - Test your movement, strength, and stability

A lateral compression test of the metatarsals can reproduce the pain. A clicking sound is sometimes heard (Mulder's sign). This test confirms the diagnosis.

You do not need to see a doctor before consulting a physical therapist. If necessary, your physical therapist will refer you.

Ultrasound or MRI scans are used if the diagnosis is uncertain or to plan surgery. These tests are rarely necessary.

How does physical therapy help Morton's neuroma?

Physical therapy is effective in 80% of cases. It combines nerve mobilization, strengthening exercises, and education.¹ Treatment works best before the fourth month of symptoms.

- Analysis of your joint mobility - Assessment of nerve gliding - Observation of your movements - Strength and stability tests

The physical therapist improves nerve gliding. It's like oiling a squeaky door. These mobilizations reduce sensitivity and pain.

Targeted exercises strengthen the intrinsic muscles of the foot (small internal muscles). They improve stabilization. This prevents the metatarsal heads from collapsing, which compresses the nerve.

You will learn to control your movements better. You will gradually desensitize your nerve.

Your physical therapist will teach you how to pace your activities to optimize healing.

A study shows that after six sessions combining massage, mobilization, exercises, and education, the pain resolved. Foot function improved.²

The physiotherapy approach to Morton's neuroma is similar to that used for other nerve conditions in the lower limb. If you also suffer from knee pain, check out our article on knee osteoarthritis to understand how joint conditions can affect the biomechanics of the entire lower limb.

The principles of manual therapy and therapeutic exercises also apply to other areas. Consult our guide to physical therapy to better understand how these approaches work.

What exercises help relieve Morton's neuroma?

Effective exercises include nerve gliding, calf stretches, strengthening the muscles of the foot, and self-massage with a ball.

Start slowly and increase gradually. If an exercise increases the pain, stop and consult your doctor.

Weeks 1-2: Focus on gentle mobilization and light stretching. The goal is to reduce nerve sensitivity without causing significant pain.

Weeks 3-4: Gradually add strengthening exercises. Start with simple movements such as picking up a towel with your toes or doing active foot arches.

Weeks 5-8: Increase the intensity and complexity of the exercises. Introduce weight-bearing exercises such as rising onto your toes, first on both feet, then gradually on one foot.

After 8 weeks: Maintain your gains with preventive exercises 2-3 times a week. If you run, gradually reintroduce running according to your physical therapist's advice.

What shoes should you wear with Morton's neuroma?

The ideal shoes are wide at the front. They have a rigid sole and a small heel (2-3 cm maximum). Avoid narrow, pointed shoes or high heels.

Orthopedic insoles with retrocapital support (under the front of the foot) are often effective. They redistribute pressure and relieve the nerve. A podiatrist or physical therapist can advise you.

Choosing the right shoes is a key part of treatment. If you run, make sure your running shoes have enough room for your toes and don't compress the front of your foot.

- Shop at the end of the day when your feet are slightly swollen - Try on shoes with the socks or stockings you usually wear - Check that there is at least 1 cm of space between your longest toe and the tip of the shoe - Walk around the store to test comfort - Don't buy shoes thinking they will stretch; they should be comfortable right away

How long does it take for Morton's neuroma to heal?

Healing typically takes 6 to 12 weeks with proper conservative treatment. Treatment works best before the 4th month of symptoms.

After 3 to 6 months without sufficient improvement, or if the neuroma measures more than 6 mm, surgery may be considered. The procedure involves releasing or removing the neuroma. An area of numbness between the toes is possible afterward, but this usually resolves within a few months.

The good news: most patients do not require surgery.

Weeks 1–2: Initial reduction in acute pain with relative rest and footwear modifications. Symptoms may fluctuate.

Weeks 3-6: Gradual improvement with exercises and mobilization. Gradual resumption of activities. Noticeable reduction in electric shocks.

Weeks 7–12: Return to normal activities. Consolidation of gains. Symptoms should be minimal or absent.

After 12 weeks: Maintenance with preventive exercises. Monitoring of risk factors (footwear, activities).

If you also have chronic pain that persists beyond this period, it may be helpful to consult our guide on chronic pain to better understand the mechanisms of persistent pain and appropriate management strategies.

What can I do at home for Morton's neuroma?

To relieve neuroma at home, temporarily reduce painful activities. Wear wider shoes. Practice transfer activities such as swimming.

- Temporarily reduce walking and running if they cause pain - Gradually resume these activities when the pain subsides - Take up swimming or cycling (these reduce stress on the area)

- If you are standing for long periods of time or waiting in line at the grocery store, take short breaks to sit down - Avoid hard surfaces

- Wear wider shoes temporarily - Use thicker insoles - Wear sandals without straps if necessary

- Apply 15-20 minutes after activities if necessary - Use a towel between the ice and your skin

- Roll a golf ball or tennis ball under your foot for 5-10 minutes a day - Gently massage the area between the affected toes - Stretch your toes by gently separating them with your fingers

If there is no improvement after 10 days, consult a physical therapist to speed up your recovery.

Self-management strategies for Morton's neuroma are similar to those used for other foot and ankle conditions. If you also have ankle pain, see our article onankle sprains for additional management tips.

For active individuals who want to understand how to adapt their workouts, our article on lower back pain in physical therapy offers principles for measuring activity levels that apply to all areas of the body. These principles of gradual progression are essential for preventing recurrence.
