Sesamoiditis

Sesamoiditis is a common ailment that affects the forefoot, typically in young people who engage in physical activity like running or dancing. Its most common symptom is pain in the ball-of-the-foot, especially on the medial or inner side. The term is a general description for any irritation of the sesamoid bones, which are tiny bones within the tendons that run to the big toe.

Like the kneecap, the sesamoids function as a pulley, increasing the leverage of the tendons controlling the toe. Every time you push off against the toe the sesamoids are involved, and eventually they can become irritated, even fractured. The primary cause of sesamoiditis is overpronation. This can be controlled via insoles. People suffering with sesamoiditis have been forced to live with the pain no longer have to put up with this condition while standing, walking or running.
