The navicular bone is located on the inside of the foot just above the arch. One in 10 people has an accessory navicular bone, which is an extra piece of bone attached to the navicular. Just like other bones, the accessory navicular bone grows and hardens in adolescence. People with an accessory navicular may experience pain and swelling from shoe pressure or from frequent sprains where the extra piece of bone attaches.Causes
Let us see the reasons why the tendon or the bone would get aggravated. Ankle or foot sprain, irritation of the bone caused by footwear, overusing the foot, quite common in athletes and dancers.

Discomfort is most often present following periods of exercise or prolonged walking or standing. The bone may be somewhat visible on the inside of the foot above the arch.

By putting pressure on the area, the doctor may determine its presence simply by the presence of pain. The muscle, joint, and the overall structure of the foot may be considered, as well as the way in which the patient walks.
