Morton's Neuroma: Symptoms, Causes, and Treatment

If you have ever felt like there is a pebble stuck inside your shoe, right under the ball of your foot, you may be dealing with Morton's neuroma. This common foot condition affects the nerve that runs between the bones near the base of your third and fourth toes, and it can turn ordinary walking into a painful chore.

At Garey Orthopedic Medical Group in Claremont, our foot and ankle team sees this condition often, especially among patients who spend long hours on their feet or wear narrow, tight shoes. The good news is that Morton's neuroma responds well to treatment once it is correctly diagnosed, and most patients across the Inland Empire never need surgery to feel better.

Because the symptoms of Morton's neuroma can mimic other forefoot problems, many patients spend months trying different shoe inserts or assuming the pain will simply pass. Understanding exactly what is happening inside the foot, and why the nerve becomes irritated in the first place, is the first step toward finding treatment that actually works rather than just masking the discomfort.

What Is Morton's Neuroma?

Morton's neuroma is not a true tumor. It is a benign thickening of the tissue that surrounds a nerve, most often located between the third and fourth metatarsal bones in the ball of the foot. According to the American Academy of Orthopaedic Surgeons (AAOS), repeated irritation or compression of this nerve causes it to swell, which then creates ongoing pain, burning, or numbness in the surrounding toes.

The condition is roughly eight to ten times more common in women than men, largely because narrow, pointed-toe shoes and high heels squeeze the front of the foot and put direct pressure on the nerve. Runners, dancers, and people whose jobs require standing on hard floors for hours also face higher risk.

Common Symptoms

• A sharp, burning pain in the ball of the foot that can radiate into the toes
• A feeling of standing on a pebble, marble, or wrinkled sock
• Numbness or tingling between the third and fourth toes
• Pain that worsens with tight shoes and improves when shoes are removed or the foot is massaged

Symptoms often start intermittently, showing up only after a long day in the wrong shoes, and gradually become more frequent and more intense as the nerve tissue continues to thicken. Some patients also notice that the pain spreads into the toes themselves or that the two affected toes feel slightly separated, a subtle sign sometimes called the Sullivan sign that experienced foot specialists look for during an exam.

What Causes It to Develop

Morton's neuroma develops gradually from repeated stress on the forefoot nerve. Anything that compresses the metatarsal bones together can trigger irritation, including tight or narrow shoes, high heels, high-impact activities like running, and structural foot issues such as bunions, hammertoes, or flat feet.

Foot mechanics matter too. People with an unusually mobile or unstable forefoot may place uneven pressure on the nerve with every step, which over months or years leads to the fibrous thickening that defines this condition. This is why our sports medicine and foot specialists always ask about footwear habits, exercise routines, and any history of prior foot injuries during an evaluation.

Occupation plays a bigger role than many patients expect. Teachers, retail workers, nurses, and warehouse employees throughout the Inland Empire who spend eight or more hours a day on concrete or tile floors are disproportionately represented among our Morton's neuroma patients, regardless of what shoes they wear off the clock. Combining prolonged standing with unsupportive footwear compounds the pressure on the nerve far more than either factor alone.

How Morton's Neuroma Is Diagnosed and Treated

Diagnosis usually starts with a physical exam. Your provider will press on the space between the toes to try to reproduce your symptoms and may perform a maneuver called the Mulder's click test, where squeezing the forefoot produces a palpable click along with pain. Ultrasound or MRI imaging can confirm the diagnosis and rule out other causes of forefoot pain, such as a stress fracture or capsulitis.

Nonsurgical Treatment

Most patients improve with conservative care. Switching to wide, low-heeled shoes with a roomy toe box takes pressure off the nerve immediately. Metatarsal pads placed just behind the ball of the foot help spread the bones apart and reduce compression, and custom orthotics can correct underlying mechanical issues. When pain is more stubborn, a corticosteroid injection can calm inflammation around the nerve and provide months of relief.

When Surgery Becomes an Option

If several months of conservative treatment do not bring meaningful relief, surgical options exist. These range from a minimally invasive release of the ligament pressing on the nerve to, less commonly, removal of the thickened nerve tissue itself. Recovery from neurectomy typically involves a few weeks in a protective shoe, and most patients return to normal activity within four to six weeks.

It is worth noting that surgery is not an all-or-nothing decision made in a single visit. Our team typically walks patients through a stepwise trial of the most conservative options first, since many people find enough relief through shoe changes and padding alone that surgery never becomes necessary. Only when pain continues to limit walking, standing, or exercise despite consistent conservative treatment does the conversation shift toward a procedure.

Preventing Morton's Neuroma From Coming Back

Because footwear is such a major driver of this condition, prevention largely comes down to what you put on your feet. Choosing shoes with a wide toe box, avoiding heels higher than two inches for long periods, and rotating athletic shoes every 300 to 500 miles all help protect the nerve from repeated compression.

If you already have flat feet, bunions, or hammertoes, addressing those issues with supportive orthotics can reduce the uneven pressure that contributes to nerve irritation in the first place. Patients throughout Claremont and the greater San Gabriel Valley who stay ahead of these mechanical issues tend to have far fewer flare-ups over time.

Simple Daily Habits That Help

• Take shoes off and stretch the toes during breaks if your job requires long hours of standing
• Rolling the foot over a frozen water bottle for a few minutes can ease inflammation after a long day
• Avoid walking barefoot on hard tile or concrete floors at home for extended periods
• Replace worn-out athletic shoes before the cushioning breaks down, even if the shoe still looks fine

The Bottom Line

Morton's neuroma can make every step feel uncomfortable, but it rarely requires surgery to resolve. With the right combination of footwear changes, padding, and targeted treatment, most patients find lasting relief. Catching the problem early, before the nerve tissue thickens further, gives you the best chance of avoiding more invasive treatment down the road.

If forefoot pain has been quietly shaping which shoes you wear or how far you are willing to walk, it is worth having it evaluated rather than working around it indefinitely. A short visit with a foot and ankle specialist can confirm the diagnosis and put you on a clear path toward relief.
