Do You Have Sesamoiditis?

That nagging pain directly under the big toe joint, especially when you push off the ground, might be more than just a passing ache. It could be sesamoiditis, which is a common condition that affects two small, pea-shaped bones located in the ball of your foot. In this article, we at CarePlus Foot & Ankle Specialists are here to tell you what these bones are and why they can become painful.

Their primary functions are to act as a lever for the tendon that helps you bend the big toe, absorb force as you walk and run, and help distribute weight away from the metatarsal.

Simply put, sesamoiditis occurs when these bones or the tendons surrounding them become inflamed due to repetitive stress.

In some cases, people may even notice localized swelling or bruising around the big toe joint and have trouble bending the big toe.

Causes of Sesamoiditis

So, how do people get it? Sesamoiditis is primarily an overuse injury that results from chronic or repetitive stress placed on the sesamoid bones. And there are many factors that lead to it, such as:
