What is it?
Morton’s Neuroma is a thickening of the tissue that surrounds the intermetatarsal nerve leading to the toes. When the nerve becomes squeezed and irritated, it causes painful symptoms. Neuroma patients occasionally complain of a “pins and needles” sensation that spreads through their fourth and fifth toes, or of a feeling akin to hitting their “funny bone.”
What causes it?
A neuroma can occur in response to the irritation of a nerve by one or more factors:
• Abnormal foot function or foot mechanics: primarily excessive pronation that causes strain on the nerve.
• Improper footwear: constricting, narrow, poor-fitting shoes with a tight or pointed toe box tend to compress the end of the foot, leading to excessive pressure in the area of the nerve. High-heeled shoes are a particular culprit here.
• Previous trauma to the foot: Those who engage in high-impact activities that bring repetitive trauma to the foot (running, aerobics, etc.) have a greater chance of developing a neuroma.
