If you have ever felt a sharp, burning pain in the ball of your foot — as though you are standing on a pebble or a folded sock — you may be dealing with a condition called Morton’s neuroma. It is one of the more common forefoot problems seen in foot and ankle practices, and it affects a wide range of people, from office workers who spend long hours in dress shoes to Treasure Valley runners logging miles on the Boise River Greenbelt.

Despite how frequently it occurs, Morton’s neuroma is often misunderstood. Many patients live with the discomfort for months before seeking care, sometimes attributing it to poorly fitting shoes or general foot fatigue. Understanding what this condition involves and when professional evaluation is warranted can help you address the problem before it significantly limits your daily activities.

What Is Morton’s Neuroma?

Morton’s neuroma is a thickening of the tissue that surrounds one of the nerves leading to the toes, most commonly the nerve between the third and fourth toes. This thickening develops in response to irritation, compression, or repeated stress on the nerve. While the term “neuroma” suggests a tumor, it is not a true tumor — it is a benign enlargement of nerve tissue that results from chronic irritation.

As the tissue around the nerve thickens, it puts pressure on the nerve itself, producing symptoms that can range from mild tingling to significant pain. The condition tends to worsen progressively if the factors contributing to it are not addressed.

Common Causes and Risk Factors

Several factors can contribute to the development of Morton’s neuroma. Footwear plays a significant role — shoes with a narrow toe box or high heels force the toes into a compressed position, increasing pressure on the nerves in the forefoot. This is one reason the condition is more commonly diagnosed in women than men.

Foot mechanics also matter. Individuals with bunions, hammertoes, flat feet, or high arches may be more susceptible because these structural variations can alter how weight is distributed across the forefoot. Repetitive activities that involve pressure on the ball of the foot — running, court sports, or even prolonged standing — can also contribute.

For active residents of Boise and the surrounding Treasure Valley communities, running on hard surfaces and wearing athletic shoes that do not provide adequate forefoot support are common contributing factors worth paying attention to.

Recognizing the Symptoms

Morton’s neuroma does not typically present with a visible lump or external sign. Instead, patients usually describe sensations such as:

• A burning pain in the ball of the foot that may radiate into the toes
• Numbness or tingling in the affected toes
• A feeling of standing on a marble, pebble, or bunched-up sock
• Pain that worsens with activity or when wearing tight shoes
• Relief when removing shoes and massaging the foot

Symptoms often develop gradually and may initially come and go. Over time, they tend to become more persistent and can make it difficult to walk comfortably, exercise, or wear certain types of footwear.

How Morton’s Neuroma Is Diagnosed

Diagnosis begins with a thorough physical examination. At Flint Foot & Ankle Institute, Dr. Flint evaluates the foot by palpating the area between the metatarsal heads, checking for a palpable click (known as a Mulder’s sign), and assessing the overall structure and mechanics of the foot.

In some cases, imaging studies such as ultrasound or MRI may be used to confirm the diagnosis and rule out other conditions that can produce similar symptoms, including stress fractures, metatarsophalangeal joint inflammation, or plantar plate injuries.

Conservative Treatment Options

The majority of Morton’s neuroma cases respond well to non-surgical treatment, particularly when addressed early. Conservative approaches focus on reducing pressure on the affected nerve and managing inflammation.

Footwear modifications are typically the first recommendation. Switching to shoes with a wider toe box and lower heel height gives the toes more room and reduces compression on the nerve. For patients who need to wear dress shoes for work, selecting styles with adequate forefoot width can make a meaningful difference.

Custom orthotics or metatarsal pads can help redistribute pressure across the ball of the foot, taking stress off the irritated nerve. These devices are designed to support the metatarsal arch and create space between the metatarsal heads where the nerve passes.

Anti-inflammatory medications, icing, and activity modification can help manage acute symptoms. In cases where conservative measures alone are not sufficient, corticosteroid injections may provide temporary relief by reducing inflammation around the nerve.

When Surgery May Be Considered

If conservative treatments do not provide adequate relief after a reasonable trial period, surgical intervention may be discussed. The most common surgical approach involves removing the thickened portion of the nerve, a procedure called a neurectomy. This is typically performed on an outpatient basis and allows patients to return to normal footwear and activities within several weeks.

Another option in select cases is a decompression procedure, which involves releasing the ligament that runs over the nerve to reduce pressure without removing nerve tissue. The best approach depends on the severity of the condition, the patient’s anatomy, and their specific goals for activity and recovery.

At Flint Foot & Ankle Institute, Dr. Flint discusses the risks, benefits, and expected recovery timeline for any surgical recommendation so patients can make informed decisions about their care.

What to Expect During Recovery

Recovery from neuroma surgery is generally straightforward. Most patients are able to bear weight in a protective shoe shortly after the procedure and transition back to regular footwear within a few weeks. Swelling in the forefoot may take several weeks to fully resolve, and temporary numbness between the affected toes is expected following a neurectomy.

Returning to high-impact activities like running or hiking is typically possible within six to eight weeks, depending on healing progress and individual factors. Physical therapy may be recommended to restore strength and flexibility in the foot.

Taking the Next Step

If you are experiencing persistent pain in the ball of your foot, tingling in your toes, or the sensation of walking on something that is not there, it may be worth having the condition evaluated. Early intervention often means simpler, more conservative treatment options and a quicker return to the activities you enjoy.
