Sesamoiditis

Sesamoiditis is a painful inflammation of the sesamoid bones in the ball of the foot. Each of your feet has two tiny, pea-shaped bones called the sesamoids. These bones are responsible for smooth movements, weight-bearing, and elevation of the big toe that allows you to push off the toe when you walk. 

When the sesamoid bones are injured, usually from repetitive overuse or from wearing the wrong shoes, a variety of symptoms follow. These typically include foot pain beneath the base of the big toe, pain while walking, swelling, redness, and warmth. It can be difficult to bear weight on the affected foot. 

Your chiropodist can diagnose sesamoiditis by examining your feet. An X-ray or MRI can be used to determine if the sesamoid bones are fractured, displaced, or affected by arthritis. A joint fluid sample may need to be taken if gout or infection is suspected. 

Conservative treatments, such as resting the foot, switching to more comfortable shoes, and wearing orthotics, are often adequate for symptom relief. Anti-inflammatory medications can be taken to manage pain while the injury heals. For more information about sesamoiditis, please consult with a chiropodist.
