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.

• Symptoms of Morton’s neuroma include:

• Feeling like ”walking on a marble”
• Persistent pain in the ball of your foot that:
  • Increases when wearing shoes or pressing on the area
  • Gets worse over time
• 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)

• 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.

• 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

• 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

Call your health care provider if you have persistent pain or tingling in your foot or toe area

• 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

• Avoid ill-fitting/tight shoes
• Avoid high heels
• Wear comfortable shoes with a wide toe box, low heels, & good arch support
• Avoid high-impact sports such as rock-climbing, ballet dancing, jogging, running, snow skiing

Nonsurgical treatment does not always improve symptoms. Surgery to remove the thickened tissue is successful in about 85% of cases.

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.
