A Mortons neuroma is an enlarged or impinged nerves most commonly found between the third and fourth metatarsal heads.
How to deal with a Morton’s neuroma
Morton’s neuroma, also known as interdigital neuroma, is a painful condition that affects the foot, specifically the area between the third and fourth toes. It involves a thickening or enlargement of the nerve that runs between the metatarsal bones of the foot. Although it is called a neuroma, it is not a true tumor but rather a benign growth of nerve tissue.
The exact cause of Morton’s neuroma is not fully understood, but it is believed to result from irritation, compression, or repetitive trauma to the nerve. Factors that may contribute to its development include:
- Footwear: Wearing tight, narrow shoes or high heels that squeeze the toes together and place excessive pressure on the ball of the foot can increase the risk of developing Morton’s neuroma.
- Foot Structure: Certain foot deformities, such as high arches or flat feet, can put added stress on the nerves and increase the likelihood of neuroma formation.
- Foot Stress and Overuse: Activities that involve repetitive stress on the feet, such as running, jogging, or participating in high-impact sports, can contribute to the development of Morton’s neuroma.
The symptoms of Morton’s neuroma can vary but typically include:
- Pain: Individuals with Morton’s neuroma often experience sharp or burning pain in the ball of the foot, specifically between the third and fourth toes. The pain may radiate into the toes and worsen with walking or wearing tight shoes.
- Numbness or Tingling: Some people may also experience numbness, tingling, or a sensation of pins and needles in the affected area.
- Feeling of a Lump: Some individuals may describe a sensation of having a small pebble or lump in their shoe.
Diagnosing Morton’s neuroma typically involves a thorough clinical examination, medical history review, and sometimes imaging studies, such as an ultrasound or MRI, to rule out other conditions. During the examination, the healthcare provider may perform specific maneuvers to elicit pain or reproduce symptoms.
Treatment options for Morton’s neuroma include both conservative and surgical approaches, depending on the severity of symptoms and the individual’s response to conservative measures. Conservative treatments may include:
- Footwear Modifications: Wearing shoes with a wide toe box and low heels can help reduce pressure on the affected area.
- Orthotic Devices: Custom-made shoe inserts (orthotics) or arch supports can help alleviate pressure and provide better foot support.
- Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) or corticosteroid injections may be prescribed to reduce pain and inflammation.
- Padding or Taping: Padding the affected area or using special taping techniques can help reduce pressure on the neuroma.
- Physical Therapy: Exercises to strengthen the foot muscles and improve foot mechanics may be recommended.
If conservative measures fail to provide relief, surgical intervention may be considered. The surgical options for Morton’s neuroma include removing the neuroma or releasing the surrounding structures to relieve pressure on the nerve.
Frequently asked questions on a Morton’s Neuroma
What is Morton’s neuroma?
It is inflammation and thickening of the tissue surrounding one of the interdigital nerves (nerves that run between the metatarsal bones and supply sensation to the toes). The most common location is the third web space (between the third and fourth toes). It can occasionally occur between the second and third toes and is rare elsewhere. The swelling irritates the nerve and causes pain.
What does it feel like / what are the symptoms?
Common symptoms include:
- Burning, sharp, stabbing, or shooting pain in the ball of the foot that may radiate into the toes.
- A sensation of walking on a pebble, marble, stone, or having a bunched-up sock in the shoe.
- Tingling, numbness, or “pins and needles” in the affected toes.
- Cramping or a feeling of fullness/pressure in the forefoot.
Symptoms usually worsen with walking, standing, or wearing tight/narrow/high-heeled shoes and improve when shoes are removed and the foot is massaged or rested. Night pain is uncommon. There is typically no visible lump, bump, or skin change.
What causes Morton’s neuroma?
The exact cause is not fully understood, but it results from repetitive irritation, compression, or microtrauma to the nerve. Contributing factors include:
- Tight, narrow, or pointed-toe shoes and high heels (which squeeze the toes and increase pressure on the ball of the foot).
- High-impact activities (running, jumping, certain sports).
- Foot deformities or biomechanical issues (bunions, hammertoes, high arches, flat feet).
- Trauma or other conditions that put pressure on the forefoot.
It is much more common in women (often linked to footwear) and typically affects people aged 30–60.
Is Morton’s neuroma cancerous or a tumor?
No. Despite the name “neuroma,” it is not a true tumor and is not cancerous. It does not turn into cancer. It is a benign thickening (perineural fibrosis) of tissue around the nerve.
How is it diagnosed?
Diagnosis is primarily clinical—based on your symptoms and a physical exam (including checking for tenderness in the web space and sometimes a “Mulder’s click” when the foot is squeezed). Imaging such as X-ray (to rule out other problems like fractures or arthritis), ultrasound, or occasionally MRI may be used if the diagnosis is unclear or to guide treatment. Ultrasound is often preferred.
Does Morton’s neuroma go away on its own?
The underlying thickening does not typically resolve completely on its own, but symptoms can improve significantly or resolve with conservative care for many people. Symptoms often come and go.
How is it treated?
Most people improve with non-surgical (conservative) measures:
- Footwear changes — Wide, deep toe-box shoes with low heels and good cushioning; avoid high heels and narrow shoes.
- Orthotics or metatarsal pads — Pads or custom insoles placed just behind the ball of the foot to spread the metatarsals and reduce pressure on the nerve.
- Activity modification (reduce high-impact activities temporarily).
- Ice, rest, and over-the-counter anti-inflammatory medications (e.g., ibuprofen) for symptom relief.
- Corticosteroid injections (to reduce inflammation) or other injections in some cases.
- Physical therapy or specific exercises in some situations.
If conservative treatment fails after a reasonable trial, surgery (most commonly neurectomy—removal of the affected portion of the nerve) may be considered. Surgical success rates are often reported in the 80–95% range, though permanent numbness in the affected toes is a common side effect, and recurrence can occur.
Can it come back after treatment or surgery?
Yes, symptoms can recur, especially if footwear or biomechanical factors are not addressed. Recurrence after surgery is possible but not the most common outcome.
Who is most at risk?
Women (roughly 5–8+ times more common than in men), people who wear high heels or tight shoes, those with certain foot shapes/deformities, and people involved in high-impact sports or activities. Excess body weight can also increase risk.
Can I prevent it or stop it from getting worse?
Wear properly fitting shoes with a wide toe box and low heels. Use orthotics or metatarsal pads if recommended. Maintain a healthy weight. Address other foot problems (bunions, etc.). Avoid prolonged high-impact activities that aggravate symptoms without proper footwear support. Early attention to symptoms helps prevent worsening.
When should I see a doctor?
See a healthcare professional (podiatrist, orthopedist, or primary care provider) if you have persistent ball-of-foot pain, especially if it interferes with walking or daily activities, does not improve with simple footwear changes, or is associated with numbness/tingling. Prompt evaluation helps rule out other causes and start effective treatment.
