What Causes Sesamoiditis?
Sesamoiditis is Caused by irritation and inflammation of the sesamoid bones, which are small, round bones located beneath the big toe joint and embedded within the tendons of the foot. The most common cause is repetitive stress placed on the forefoot, particularly activities that involve pushing off the toes, such as running, dancing, jumping, or wearing footwear that places excessive pressure on the ball of the foot. Over time, this repeated loading can overwhelm the body’s ability to recover, leading to ongoing inflammation in the surrounding tendons and tissues.
Certain structural and lifestyle factors can also contribute to the development of sesamoiditis. High arches, altered walking patterns, or uneven weight distribution across the foot can increase stress on the sesamoid bones. Wearing thin-soled shoes, high heels, or footwear with limited cushioning may further intensify pressure in this area. Sudden increases in activity level, prolonged standing, or training on hard surfaces can also play a role. In many cases, sesamoiditis develops gradually as a result of cumulative strain rather than a single event, making early recognition and modification of contributing factors important for managing symptoms.
