(Mortons) Neuroma is a benign tumor of the nerve, most commonly occurring between the third and fourth toes. It is the thickening of the nerve tissue as it passes under the ligament connecting the toe bones in the forefoot.

Causes and risk factors

  • Irritation
  • Trauma
  • Excessive pressure on the area
  • More likely to occur in women than men


  • Usually no visible signs
  • Burning in the ball of the foot
  • Intensified pain with activity and wearing shoes
  • Numbness in the toes

Diagnosis and treatment

Studies have shown that switching to a wider shoe can reduce pressure on the nerve and give it time to heal. Custom shoe inserts may also relieve irritation and reduce pain. If symptoms persist, your orthopedic surgeon may suggest an injection to reduce swelling and inflammation.
