Morton’s Neuroma

Overview

Morton’s neuroma is a painful condition affecting the ball of the foot, most often between the third and fourth toes. It occurs when tissue around one of the nerves leading to the toes becomes thickened or irritated. Although it is called a “neuroma,” it is not a cancer. It is usually related to nerve compression and inflammation in the forefoot.

People with Morton’s neuroma often describe the feeling as if they are walking on a small pebble, a fold in the sock, or a bunched-up area inside the shoe. The discomfort may come and go at first, especially with certain shoes or activities. Over time, symptoms can become more persistent if the nerve remains irritated.

Morton’s neuroma is commonly managed by orthopedic specialists, foot and ankle surgeons, and other healthcare professionals with expertise in foot conditions. Treatment depends on the severity of symptoms, foot structure, activity level, and how long the problem has been present.

Symptoms

The main symptom of Morton’s neuroma is pain in the ball of the foot. This pain may spread into the toes and may feel sharp, burning, tingling, or cramping. Some people also experience numbness in the affected toes.

Symptoms often become more noticeable when wearing tight, narrow, or high-heeled shoes, or during activities that put pressure on the forefoot. Removing the shoe, resting, or gently massaging the area may temporarily ease discomfort for some people.

Common symptoms may include:

• Burning or sharp pain in the ball of the foot
• Tingling or numbness in the toes
• A feeling of standing on a pebble or lump
• Pain that worsens with walking, running, or tight footwear
• Discomfort that improves when shoes are removed

There is usually no visible lump on the outside of the foot. Swelling may be minimal or absent, even when symptoms are significant.

Causes and Risk Factors

Morton’s neuroma develops when a nerve in the forefoot is repeatedly compressed, stretched, or irritated. This may lead to thickening of the tissue around the nerve, causing pain and abnormal sensations.

Several factors can increase the likelihood of nerve irritation in the ball of the foot. Footwear is a common contributor. Shoes with a narrow toe box can squeeze the toes together, while high heels shift body weight forward and increase pressure on the forefoot.

Risk factors may include:

• Wearing tight, narrow, or high-heeled shoes
• High-impact activities that stress the forefoot
• Foot shapes such as flat feet or high arches
• Bunions, hammertoes, or other toe deformities
• Previous injury or repeated stress to the forefoot

Not everyone with these risk factors will develop Morton’s neuroma, and symptoms can vary widely from person to person. A professional evaluation is important because other foot conditions can cause similar pain.

Diagnosis

Diagnosis usually begins with a discussion of symptoms, footwear, activity level, and medical history. The doctor may ask where the pain is located, when it occurs, and what makes it better or worse.

During a physical examination, the healthcare professional may press on specific areas of the foot, check toe sensation, and assess foot alignment. Certain movements or pressure between the metatarsal bones may reproduce the symptoms. Sometimes a clicking sensation can be felt during examination, although this is not always present.

Imaging tests may be recommended when the diagnosis is unclear or when other conditions need to be ruled out. These may include X-rays to evaluate bone-related problems, or ultrasound or magnetic resonance imaging to assess soft tissues and the nerve area. The choice of test depends on the individual situation and clinical findings.

Because conditions such as stress fractures, arthritis, joint inflammation, tendon problems, or nerve-related disorders can mimic Morton’s neuroma, an accurate diagnosis by a qualified healthcare professional is important before treatment decisions are made.

Treatment Options

Treatment for Morton’s neuroma aims to reduce pressure on the affected nerve, relieve pain, and improve walking comfort. Many people begin with non-surgical approaches, especially when symptoms are mild or recent.

Conservative treatment may include changes in footwear, such as choosing shoes with a wider toe box, lower heel, and better cushioning. Supportive shoe inserts or custom orthotic devices may help redistribute pressure across the foot. Padding may also be used to reduce stress in the painful area, depending on a specialist’s recommendation.

Activity modification may be advised if certain movements or sports worsen symptoms. A healthcare professional may also suggest physical therapy to address foot mechanics, flexibility, and load distribution. In some cases, injections may be considered to reduce inflammation and discomfort around the irritated nerve.

If symptoms continue despite appropriate non-surgical care, surgical treatment may be discussed. Surgical options may involve releasing structures that compress the nerve or removing the thickened nerve tissue. The most suitable approach depends on the patient’s symptoms, examination findings, imaging results, and overall health.

Recovery and symptom improvement vary. A healthcare professional can explain expected recovery time, possible risks, and activity restrictions based on the chosen treatment.

When to See a Doctor

Medical advice is recommended if pain in the ball of the foot persists, returns frequently, or interferes with walking, work, sports, or daily activities. Early evaluation may help identify the cause and prevent symptoms from worsening.

You should see a doctor if you experience ongoing burning pain, tingling, numbness, or a persistent sensation of a lump or pebble under the foot. It is also important to seek care if symptoms do not improve after changing footwear or reducing activities that aggravate the pain.

Prompt medical assessment is especially important if foot pain follows an injury, if there is significant swelling, redness, or inability to bear weight, or if there are changes in skin color or sensation. People with diabetes, circulation problems, or known nerve conditions should seek medical guidance for any new or worsening foot symptoms.

A specialist can evaluate the foot, confirm the cause of symptoms, and discuss safe treatment options tailored to the individual patient.
