WHAT ARE THE CAUSES & RISK FACTORS?
Morton’s neuroma is frequently caused by shoes that are too small or have high heels. These shoes can cause nerve compression or irritation in your feet. As a result of the pressure on the irritated nerve, it thickens and gradually becomes more painful.
A foot or gait abnormality is another possible cause, which can lead to instability and put pressure on a nerve in your foot.
