Morton's Neuroma: Why the Ball of Your Foot Burns and What to Do About It

You take off your shoe after a long day and squeeze the front of your foot - instant relief. But during the day, every step brings a burning, electric sensation between your toes. Maybe it feels like a marble or pebble stuck under the ball of your foot, or like your sock is bunched up when it isn't. If this sounds familiar, there is a strong chance you have Morton's neuroma - one of the most common and most misunderstood foot conditions we treat at Vertex Podiatry in Columbus.

What Is Morton's Neuroma?

Despite the name, Morton's neuroma is not a tumor. It is a thickening and enlargement of the plantar digital nerve - the nerve that runs between the long bones of the foot (metatarsals) and provides sensation to the toes. Most commonly it affects the nerve between the third and fourth metatarsal heads, though it can occur between the second and third as well.

When the nerve is repeatedly compressed or irritated - by tight shoes, repetitive impact, or abnormal foot mechanics - the body responds by laying down scar-like fibrous tissue around the nerve. Over time, this thickening makes the nerve even more sensitive to pressure, creating a cycle of pain that worsens with activity and improves with rest.

Symptoms: What a Neuroma Feels Like

The classic presentation is very specific:

• Burning, stinging, or sharp pain in the ball of the foot, usually between the 3rd and 4th toes
• "Pebble in the shoe" sensation - the feeling of standing on something, even when nothing is there
• Numbness or tingling that radiates into the adjacent toes
• Pain that worsens with tight shoes or high heels and eases after removing footwear and massaging the foot
• Symptoms that build gradually over months before becoming persistent

A hallmark clinical finding is the Mulder's click - when a physician squeezes the forefoot from side to side, a click and reproduction of pain can be felt in the affected space. This test, combined with your history, is often enough to confirm the diagnosis without imaging.

What Causes It?

Morton's neuroma develops when the nerve is subjected to chronic irritation or compression. Common contributing factors include:

• Narrow or pointy-toed shoes that compress the forefoot
• High heels, which transfer body weight forward onto the metatarsal heads
• High-impact sports such as running, basketball, or tennis - particularly on hard surfaces
• Foot structure abnormalities including bunions, hammertoes, flat feet, or high arches, which can increase pressure on specific parts of the forefoot
• Prior foot injury that caused local scar tissue or altered mechanics

Women are diagnosed with Morton's neuroma at a significantly higher rate than men - primarily because of the prevalence of narrow, high-heeled footwear.

How Is It Diagnosed?

Diagnosis is primarily clinical. Dr. Golan will perform a detailed physical examination including palpation of the intermetatarsal spaces, compression tests, and range-of-motion assessment. Ultrasound imaging is often used to confirm the presence and size of the neuroma - it is cost-effective, radiation-free, and can be performed in-office. MRI may be ordered in complex or atypical cases.

Treatment Options

The vast majority of Morton's neuromas respond to conservative treatment, especially when addressed before the nerve becomes severely thickened.

Step 1 - Footwear modification: Switching to wider shoes with a roomy toe box takes pressure off the intermetatarsal space immediately. This alone relieves symptoms in many patients with mild neuromas.

Step 2 - Metatarsal padding and orthotics: A custom orthotic or a simple metatarsal pad repositions the metatarsal heads slightly, reducing pinch on the nerve with every step.

Step 3 - Corticosteroid injection: A precisely placed cortisone injection reduces the inflammation around the nerve and can provide months of relief. Ultrasound guidance ensures accurate delivery. This is effective for moderate neuromas and can be repeated if needed.

Step 4 - Alcohol sclerosing injections: A series of dilute alcohol injections gradually desensitizes and shrinks the nerve tissue. Studies show 60-80% success rates and this approach avoids surgery entirely for many patients.

Step 5 - Surgical neurectomy: When conservative measures have been exhausted, the neuroma can be surgically removed through a small incision. This is a minimally invasive outpatient procedure with excellent outcomes. The affected toes will have some permanent numbness, but patients consistently report this is far preferable to the pain.

When Should You See a Podiatrist in Columbus?

Do not wait until the pain becomes severe. Neuromas that are treated early - when the nerve thickening is minimal - respond much better to conservative measures. If you have had burning or numbness in the ball of your foot for more than a few weeks, especially if it comes on with walking and improves with rest and shoe removal, book an evaluation.
