What is Sesamoiditis?
If you are experiencing foot pain under your big toe, you may be suffering from sesamoiditis.
Most bones in the human body connect at the joints. However, a few, such as the kneecap (patella) and two smaller bones (the size of peas!) in the underside of your foot, are different.
Instead, these bones connect to tendons or are embedded in muscle, which act like pulleys. One of these small bones is near your big toe, one is on the outer side of the foot and the final one is closer to the middle of the foot.
These bones are called sesamoids and help with both weight-bearing and elevating the bones in your toe.
As with the other bones in your body, sesamoids can break or become irritated, painful and/or inflamed. The pain can also become intensified when you walk — especially in high heels or shoes that have no support in the sole.
Sesamoiditis can be a common condition in runners and dancers.
