Morton’s Neuroma Symptoms, Causes, and Treatment

You feel a burning or tingling sensation under the ball of the foot, usually between the third and fourth toes. Tight enclosed shoes set it off. Pulling off your shoes and massaging the foot offers quick relief. As it progresses, the pain becomes sharp and shooting, radiating into the toes, and a numb patch develops between the toes. Walking long distances in dress shoes or high heels becomes something you start to avoid.

Morton’s neuroma is a thickening of the tissue surrounding one of the digital nerves in the forefoot, most often the nerve running between the third and fourth toes. It is sometimes described as a benign nerve growth, but the underlying problem is chronic mechanical irritation of the nerve, not a tumour. The symptoms are distinctly neurological, which sets it apart from other causes of forefoot pain. Identifying it early opens the door to conservative treatment before more invasive options are needed.

Symptoms of Morton’s Neuroma

The symptom pattern is fairly specific and helps separate Morton’s neuroma from other forefoot conditions. Pain is usually neurological in character rather than a deep ache.

• Sharp, stabbing, or shooting pain at the ball of the foot, often between the third and fourth toes.
• Burning sensation across the affected area, sometimes spreading into the toes.
• Numbness or tingling in the two adjacent toes.
• A feeling of standing on a fold in the sock or a small pebble.
• Symptoms worse in narrow, tight, or enclosed footwear, and improved by removing the shoe.
• A clicking or palpable lump (Mulder’s click) when the forefoot is squeezed side to side.
• Pain that may radiate proximally up into the foot during longer walks.

Causes of Morton’s Neuroma

Morton’s neuroma develops because the digital nerve is repeatedly irritated as it passes between the metatarsal heads. Anything that increases compression or stretch on the nerve raises the risk. Several factors typically combine before symptoms appear.

What Causes Morton’s Neuroma?

• Compression of the forefoot from narrow toe boxes, high heels, or tight enclosed shoes.
• Biomechanical instability of the forefoot, including excess pronation or first ray instability, which “pinches” the nerve during gait.
• Repetitive trauma from high-impact sports, running, and racquet sports.
• Direct trauma to the forefoot, including landing from a height or stubbing the toe.
• Forefoot deformities that crowd the metatarsal heads, including bunions and hammer toes.

Who Carries a Higher Baseline Risk?

• People with flat feet or high arch feet, both of which alter forefoot loading.
• Regular wearers of high heels or narrow-toed footwear.
• Runners, dancers, and racquet sport players.
• Women in their 40s and 50s, who are more commonly diagnosed.
• People with previous forefoot fractures or surgery.

Conditions Commonly Mistaken for Morton’s Neuroma

Pain in the same general area can come from several different structures. A careful examination separates the diagnoses.

Metatarsalgia

General pain across the ball of the foot from joint or fat pad irritation can mimic a neuroma, though metatarsalgia tends to spread across the forefoot rather than radiate into the toes.

Plantar plate injury

A plantar plate injury usually sits under the second toe and produces pain on the underside of the joint rather than the burning or tingling of a neuroma.

Metatarsophalangeal joint capsulitis or synovitis

Inflammation of the joint capsule or lining causes localised pain and swelling around a single toe joint, without the electric, radiating quality typical of a neuroma.

Stress fracture of a metatarsal bone

A stress fracture in one of the metatarsal bones produces pain that worsens with weight-bearing and often has a pinpoint tender spot over the bone itself.

Intermetatarsal bursitis

An inflamed bursa between the metatarsal heads can sit very close to where a neuroma forms, which is why the two are easily confused on symptoms alone.

Treating and Preventing Morton’s Neuroma

Treatment targets the irritation around the nerve and the mechanical factors that caused the irritation in the first place. Most cases respond well to conservative care, especially when symptoms are addressed early, so the priority is to take pressure off the nerve and calm it before more invasive options are considered.

Conservative treatment

Conservative care combines offloading the nerve, calming the irritation, and correcting the mechanics that drove it.

• Footwear: Switching to footwear with a wide and deep toe box and avoiding high heels and narrow shoes reduces compression on the nerve.
• Customised foot orthoses: With a metatarsal dome positioned to spread the metatarsal heads apart and offload the nerve.
• Activity modification: Relative rest from high-impact activities and avoiding barefoot walking on hard floors during a symptomatic period.
• Extracorporeal shockwave therapy: Used to reduce nerve irritation and inflammation.
• Magnetotransduction therapy (EMTT): Also used to reduce nerve irritation and inflammation.
• Anti-inflammatory medication: Where appropriate and under medical advice, to ease pain and inflammation.

When conservative care isn’t enough

Where symptoms persist despite footwear, orthoses, and the measures above, a steroid injection or an alcohol sclerosing injection may be offered in selected cases, generally after conservative care has been tried. Surgical excision of the neuroma is considered when symptoms persist despite a full course of conservative care. It carries a risk of permanent numbness in the affected web space, which is worth understanding before deciding (see side effects of Morton’s neuroma surgery). Where surgery is the right pathway, a referral to an orthopaedic surgeon is arranged.

Preventing recurrence

• Long-term footwear changes, particularly in working environments where heels or narrow shoes are habitual.
• Continued use of orthoses where biomechanical factors are unlikely to change.
• Reviewing training load and surfaces for athletes.
