Morton's Neuroma is the 'squeezing' of the nerve placed between the 3rd and 4th metatarsal bones. Morton's Neuroma is very similar to Metatarsalgia, but in addition displays symptoms like numbness and a tingling sensation in the toes. It can be quite painful at times.
A neuroma is a benign tumour of a nerve. Morton's Neuroma is not actually a tumour, but a thickening or swelling of the tissue that surrounds the digital nerve leading to the toes.
