Foot Conditions A-Z
A Morton's neuroma is a benign (non-cancerous) enlargement of part of a nerve that typically occurs between the third and fourth toes, just below their bases (between the third and fourth metatarsal bones); it may also occur between the second and third toes. Nerve enlargement is usually the result of compression and irritation. The pain associated with a Morton's neuroma generally occurs gradually, but gets worse over time. These neuromas are more common in women than men.
