Sesamoiditis

Sesamoiditis is a common ailment of the plantar forefoot, causing pain in the ball of the foot specifically under the big toe joint. The sesamoid bones are very small bones which are located under the big toe joint within the tendons that run to the big toe. They are similar to the kneecap, acting to increase the leverage of the tendons that control the big toe. Due to their location and function, they are subjected to massive pressure and forces every time the big toe is used to push the foot forward.
