A Morton’s neuroma is a nonmalignant enlargement of a plantar digital nerve at the level of the metatarsal head. The plantar digital nerve can be a branch of the medial or lateral plantar nerve that comes from the tibial nerve. Repetitive trauma at the level of the metatarsal head of the plantar digital nerve causes perineural fibrosis and edema of the endoneurium of the nerve.
In fact, the term neuroma is inaccurate because there is no proliferation of axons with an interdigital neuroma. Symptoms of a Morton’s neuroma are forefoot pain and the feeling of ambulating on a pebble. These symptoms worsen with ambulation and improve with rest.
