Morton's Neuroma Underlying Cause
The cause of Morton's neuroma is unknown. However, Morton's neuroma seems to occur when a nerve in the foot is irritated or inflamed. The nerve may become inflamed due to an injury, or due to pressure against the nerve. Persistent inflammation or irritation results in overgrowth and thickening of a portion of the nerve.
Causes of Morton's neuroma may include:
- Foot injury
- Running, jumping, or climbing
- Wearing high heeled shoes
- Wearing tight fitting shoes
