Morton's Neuroma: A Podiatrist's Guide to Causes, Symptoms and Treatment

Morton's neuroma is one of the most common causes of pain in the ball of the foot. It most often affects the area between the third and fourth toes and can make walking, exercising and even standing uncomfortable.

Many people describe the sensation as feeling like they're standing on a pebble or that there's a fold in their sock. Others experience burning pain, tingling or numbness that radiates into the toes.

Although Morton's neuroma can affect anyone, it is more commonly diagnosed in women and is often associated with footwear that places increased pressure on the front of the foot.

What Is Morton's Neuroma?

Morton's neuroma is a thickening of the tissue surrounding one of the small nerves that runs between the metatarsal bones in the forefoot.

As this tissue thickens, the nerve can become irritated, leading to pain and altered sensation in the toes.

Despite the name, a Morton's neuroma is not usually a tumour. Instead, it is considered an enlargement or thickening of the tissue surrounding the nerve.

What Causes Morton's Neuroma?

Morton's neuroma develops because of repeated irritation or compression of the nerve over time.

Several factors may contribute.

Footwear

Shoes with a narrow toe box or high heels can increase pressure on the forefoot and place additional stress on the nerve.

Foot Structure

Certain foot types may increase the likelihood of developing Morton's neuroma, including:

Flat feet High arches Bunions Hammer toes Foot mechanics that increase pressure beneath the forefoot

Repetitive Activities

Activities involving repeated impact through the forefoot, such as:

Running Tennis Basketball Netball Long-distance walking

may contribute to irritation of the nerve.

Previous Injury

Previous trauma or injury to the forefoot may alter foot mechanics and contribute to ongoing irritation.

Common Symptoms

Symptoms often develop gradually and may come and go before becoming more persistent.

Common symptoms include:

Burning pain in the ball of the foot Tingling or numbness in the toes Pain between the third and fourth toes A feeling of standing on a pebble or folded sock Pain that worsens in tight shoes Relief after removing footwear or massaging the foot

How Is Morton's Neuroma Diagnosed?

A podiatrist will begin with a detailed history and physical examination.

This may include:

Assessing foot structure and walking pattern Feeling between the metatarsal bones for tenderness Performing clinical tests such as Mulder's sign Assessing footwear

If required, imaging such as ultrasound or MRI may be recommended to help confirm the diagnosis or exclude other causes of forefoot pain.

Treatment Options

Many people experience significant improvement without surgery.

Footwear Changes

Changing to shoes with:

A wider toe box Lower heels Good cushioning Adequate forefoot width

may reduce pressure on the affected nerve.

Orthotics and Metatarsal Pads

For some people, orthotics or metatarsal pads may help redistribute pressure beneath the forefoot and improve comfort during walking.

A podiatrist can advise whether these products are appropriate for your individual foot type.

Activity Modification

Temporarily reducing activities that aggravate symptoms may allow the irritated tissues to settle.

Lower-impact activities such as cycling or swimming may be more comfortable while symptoms improve.

Ice

Applying a cold pack for 5–10 minutes after activity may help reduce discomfort.

Professional Treatment

If symptoms persist, your podiatrist may discuss additional treatment options, which could include:

Footwear modification Orthotic therapy Padding or taping Referral for imaging if required Referral to another healthcare professional for consideration of injection therapy or surgical opinion where appropriate

When Is Surgery Considered?

Surgery is generally reserved for people whose symptoms remain significant despite appropriate conservative treatment.

The aim of surgery is to relieve pressure on the affected nerve or remove the thickened nerve tissue where appropriate.

Your surgeon will discuss the risks and benefits if surgery is being considered.

Can Morton's Neuroma Be Prevented?

While it cannot always be prevented, you may reduce your risk by:

Wearing shoes with adequate toe room Avoiding prolonged use of high heels Managing underlying foot mechanics where appropriate Using orthotics if recommended by your podiatrist Gradually increasing training loads

Frequently Asked Questions

Is Morton's neuroma permanent?

Not necessarily. Many people experience significant improvement with appropriate footwear, activity modification and conservative treatment. Some people may continue to have recurring symptoms.

Can Morton's neuroma go away without surgery?

Many cases improve without surgery, particularly when diagnosed early and managed appropriately.

What shoes are best for Morton's neuroma?

Shoes with a wide toe box, good cushioning and lower heels are generally the most comfortable.

Are orthotics helpful?

For some people, orthotics or metatarsal pads may help improve comfort by redistributing pressure beneath the forefoot.

Can I still exercise?

Yes. Many people continue exercising by modifying activities that aggravate symptoms and choosing lower-impact alternatives while symptoms settle.

When should I see a podiatrist?

You should seek assessment if you have persistent pain in the ball of your foot, numbness in your toes or symptoms that interfere with walking or exercise.

Conclusion

Morton's neuroma is a common cause of forefoot pain that can often be managed successfully without surgery. Early assessment, appropriate footwear, pressure-relieving products and activity modification can all play an important role in improving comfort and helping you stay active.

If you're experiencing ongoing pain in the ball of your foot, a podiatrist can help determine whether Morton's neuroma is the cause and recommend the most appropriate treatment plan for your individual needs.
