Morton's neuroma is a growth that develops on a nerve at the base of the toes. This benign (noncancerous) growth develops when a nerve becomes pinched between the toe joints, toe knuckles, and the shoe, and the constant irritation to the pinched nerve causes it to swell and grow.

Symptoms may include:

• Pain.
• Numbness.
• Cramping.
• A burning sensation that spreads into the involved toes.
• A lump between the bases of the toes.

Home treatment, such as rest, massage, and wearing roomy footwear, may help relieve symptoms. In severe cases, surgery may be needed.
