A neuroma is a pinched nerve occurring at the ball of your foot. This pinched nerve can be located between the ends of two bones or between a ligament and the end of a bone. The base of the second and third or third and fourth toes is where a neuroma is most likely to occur. A dull or sharp pain in the ball of your foot is the most common symptom of a neuroma. Other symptoms include pain between the toes where the neuroma is located, tingling in your toes, numbness in your toes and the feeling that you are standing on a stone. You will most likely notice these symptoms after standing or walking for an extended period of time. A neuroma is caused by tight or high-heeled shoes. The bones in the ball of the foot are squeezed together and result in the pinched nerve. Neuromas can also be caused by repeated blows to the ball of the foot.
