The sesamoids are two pea-shaped bones under the big toe joint. They can become painful in repetitive activities that place pressure on the ball of the foot or involve repeated upward flexion of the big toe. Sesamoiditis is an inflammatory condition caused by abnormal weight bearing on these small bones.
The diagnosis of sesamoiditis is easily made as pressure on these small bones produces pain.
This condition responds very well to simple weight deflection off the sesamoids. This is done with either temporary or permanent Orthotics, depending on the underlying cause.
Pain will increase and walking will become difficult as this is a propulsive part of the foot.
