Overview
Morton's neuroma is a thickening of nerve tissue between the toes. It commonly affects the nerve that travels between the third and fourth toes.
What are the symptoms of Morton's neuroma?
- Symptoms of Morton's neuroma include:
- Tingling in the space between the third and fourth toes
- Toe cramping
- Sharp, shooting, or burning pains in the ball of your foot (and sometimes toes)
- Pain that increases when wearing shoes or pressing on the area
- Pain that gets worse over time
- In rare cases, nerve pain occurs in the space between the second and third toes. This is not a common form of Morton's neuroma, but treatment is similar.
What causes Morton's neuroma?
- Morton's neuroma is more common in women than men.
- The exact cause is unknown. However, some experts believe the following may play a role in the development of this condition:
- Abnormal positioning of toes
- Flat feet
- Forefoot problems, including bunions and hammer toes
- High foot arches
- Tight shoes and high heels
How to know you have a Morton's neuroma?
- A foot x-ray may be done to rule out bone problems.
- MRI or high-resolution ultrasound can successfully diagnose Morton's neuroma.
- Nerve testing (electromyography) cannot definitely diagnose Morton's neuroma, but may be used to rule out conditions that cause similar symptoms.
- Your doctor may order blood tests to check for inflammation-related conditions, including certain forms of arthritis.
When to seek urgent medical care
Call your health care provider if you have persistent pain or tingling in your foot or toe area.
Treatment options
- Nonsurgical treatment is tried first. Your doctor may recommend any of the following:
- Padding and taping the toe area
- Shoe inserts
- Changes to footwear (for example, shoes with wider toe boxes)
- Anti-inflammatory medicines taken by mouth or injected into the toe area
- Nerve blocking medicines injected into the toe area
- Other painkillers
- Physical therapy
- Anti-inflammatories and painkillers are not recommended for long-term treatment.
- In some cases, surgery may be needed to remove the thickened tissue. This can help relieve pain and improve foot function. Numbness after surgery is permanent, but should not be painful.

Directions to Hospitals Treating Morton's neuroma
Prevention
Avoid ill-fitting shoes. Wear shoes with a wide toe box.
What to expect (Outlook/Prognosis)
Nonsurgical treatment does not always improve symptoms. Surgery to remove the thickened tissue is successful in about 85% of cases.
Possible complications
Morton's neuroma can make walking difficult. Persons with this foot condition may also have trouble performing activities that put pressure on the foot, such as pressing the gas pedal of an automobile. It may hurt to wear certain types of shoes, such as high-heels.
