What Are the Symptoms of Morton’s Neuroma and How Does It Feel?

Morton’s neuroma is a painful condition affecting one of the nerves in the forefoot, most commonly the nerve between the third and fourth toes. Despite its name, Morton’s neuroma is not actually a tumour. Instead, it involves thickening and irritation of the tissue surrounding a digital nerve, often associated with repeated pressure or compression in the forefoot.

One of the most distinctive features of Morton’s neuroma is the unusual way the pain can feel. Many people describe it as though they are walking on a small pebble, marble or stone inside their shoe, even when there is nothing there.

What Does Morton’s Neuroma Feel Like?

The symptoms of Morton’s neuroma can vary from person to person, but pain and abnormal sensations in the ball of the foot are among the most common.

According to Mayo Clinic, the pain may be sharp or burning and can be accompanied by pain, tingling or numbness spreading into the toes.

Common descriptions include:

• A sharp or burning pain in the ball of the foot
• A sensation of having a pebble, marble or stone inside the shoe
• Tingling or pins and needles in the toes
• Numbness affecting two adjacent toes
• Shooting or electric-like pain extending toward the toes
• A feeling of pressure or fullness beneath the forefoot
• Pain that becomes worse when walking, running or standing
• Discomfort when wearing tight or narrow shoes

The pain is usually located between the toes rather than directly underneath a particular toe. In many cases, it occurs between the third and fourth toes, although the area between the second and third toes can also be affected.

The American Academy of Orthopaedic Surgeons (AAOS) identifies pain in the ball of the foot, particularly during weight-bearing activities, as the most common symptom.

Why Does Morton’s Neuroma Hurt More When Walking?

Walking and other weight-bearing activities can increase pressure around the affected nerve. Activities involving repeated pushing off through the forefoot, such as running, jumping or fast walking, may therefore aggravate symptoms.

Shoes can make a significant difference as well. High heels and narrow footwear can squeeze the forefoot and increase pressure around the metatarsal bones and the affected nerve.

The Mayo Clinic’s treatment guidance recommends avoiding high heels and choosing shoes with a wide toe box. Mayo Clinic also notes that shoe inserts can be used to cushion and support the forefoot.

Interestingly, symptoms may improve relatively quickly when the pressure is removed. Some people notice that taking off their shoes or resting provides significant relief.

Can Morton’s Neuroma Cause Numbness or Tingling?

Yes. Because Morton’s neuroma involves irritation and thickening around a nerve, neurological symptoms such as tingling, pins and needles and numbness are common.

These sensations typically occur in the toes supplied by the affected nerve. Someone may therefore experience burning or pain in the ball of the foot together with numbness extending into the adjacent toes.

The AAOS overview of Morton’s Neuroma lists numbness and unpleasant tingling in the toes among the characteristic symptoms.

Is There a Lump on the Foot?

Usually, no.

Unlike some other foot conditions, Morton’s neuroma generally does not produce an obvious lump that can be seen from the outside. The thickening occurs deeper within the forefoot.

This is one reason the condition can sometimes be difficult to identify based purely on appearance. A person may have significant pain and nerve symptoms while the foot looks completely normal.

The AAOS notes that there are normally no outwardly visible signs, such as a lump or skin discoloration, associated with Morton’s neuroma.

Does Morton’s Neuroma Hurt All the Time?

Not necessarily.

For many people, symptoms are most noticeable during activities that put pressure on the forefoot. Walking, running, prolonged standing and wearing particular shoes can trigger or increase the pain.

Rest may reduce the symptoms.

A clinical study published in Foot and Ankle Surgery examined patients with surgically confirmed Morton’s neuroma. The researchers found that 91% experienced pain during weight-bearing, while 81% experienced relief with rest. Direct tenderness over the affected area was present in all of the patients studied.

You can read the full study, “Morton’s neuroma: A clinical versus radiological diagnosis” on PubMed.

This pattern — pain with pressure or activity followed by relief when the foot is unloaded — can therefore be an important clinical clue.

What Makes Morton’s Neuroma Symptoms Worse?

Several factors can aggravate symptoms, particularly anything that increases pressure or compression around the forefoot.

Narrow shoes

Tight footwear can compress the toes and the area around the metatarsal bones.

High heels

High-heeled shoes shift more body weight toward the forefoot and can increase pressure around the affected nerve.

Running and high-impact exercise

Repetitive loading of the forefoot can aggravate symptoms, particularly during activities involving forceful push-off.

Prolonged standing

Spending long periods on your feet may increase discomfort by continually loading the forefoot.

Push-off activities

Sports and activities that repeatedly load the front of the foot can be particularly uncomfortable.

The AAOS clinical guide to Morton’s Neuroma specifically notes that high-heeled and tight, narrow shoes can aggravate the condition.

How Is Morton’s Neuroma Diagnosed?

A healthcare professional will generally begin with your symptoms and a physical examination.

The location, type and duration of the pain are important. Your clinician may also press around the spaces between the metatarsal bones and compress the forefoot to see whether this reproduces your symptoms.

A clicking sensation known as a Mulder’s click may sometimes be present.

Imaging isn’t always necessary. The previously mentioned clinical study found that clinical assessment had a sensitivity of 98% in its group of patients with surgically confirmed Morton’s neuroma.

The researchers concluded that imaging was particularly useful when the diagnosis was unclear or when more than one web space was affected. You can see the study details on PubMed.

Ultrasound or MRI may nevertheless be used when further investigation is appropriate or when other causes of forefoot pain need to be ruled out.

What Can Help Relieve Morton’s Neuroma Symptoms?

The first approach is often to reduce pressure on the affected area.

This can include changing to shoes with a wide toe box, avoiding high heels, reducing activities that aggravate symptoms and considering an appropriate shoe insert or orthotic.

According to Mayo Clinic’s diagnosis and treatment information, changing footwear and using ready-made or custom-made shoe inserts that cushion and support the forefoot can form part of conservative treatment.

The AAOS likewise lists footwear changes, orthoses and metatarsal pads among initial non-surgical treatment options.

For more detailed information about Morton’s neuroma, including its causes, symptoms and treatment options, see the Footlogics guide to Morton’s Neuroma.

If symptoms persist despite changing footwear and reducing aggravating activities, it is sensible to seek professional assessment. Persistent forefoot pain can have several possible causes, and obtaining the correct diagnosis is important before choosing a treatment.

The Bottom Line

Morton’s neuroma often produces a distinctive combination of symptoms: burning or sharp pain in the ball of the foot, a sensation of walking on a pebble or marble, and tingling or numbness extending into the toes.

Symptoms are frequently aggravated by walking, running, prolonged standing, high heels and narrow footwear, while removing the shoes and resting may provide relief.

Although these symptoms can strongly suggest Morton’s neuroma, other conditions can cause similar forefoot pain. If pain, numbness or tingling persists, a podiatrist, doctor or other qualified healthcare professional can help determine the underlying cause and recommend appropriate treatment.
