Morton’s neuroma is a common and painful condition affecting the base of the toes, usually the third and fourth toes. The pain is sharp and sever and will suddenly set-in while walking, because the nerve that divides the bones of each toe becomes irritated or compressed. Anyone can develop Morton’s neuroma, but the condition is much more common in women who wear high-heeled shoes, people who regularly do sports or those who have a particular foot shape, such as a high arch or a flattened foot.
