Sesamoiditis is a condition characterized by pain and inflammation around the sesamoid bones, which are small bones located within the tendons that connect to the big toe. These bones act as a lever, allowing the big toe to move up and down and play a key role when pushing off during activities like walking.

Causes of Sesamoiditis

Sesamoiditis is commonly caused by pressure or trauma to the sesamoid bones. Since these bones are located in a weight-bearing part of the foot, overuse or excessive pressure can lead to inflammation and pain. Runners, for example, may develop sesamoiditis after running uphill or increasing their workout intensity. Individuals with high-arched feet or those who frequently wear high heels are also at higher risk, as these factors place extra pressure on the balls of the feet.

Symptoms of Sesamoiditis

The symptoms of sesamoiditis develop gradually and may include:

  • Pain in the ball of the foot, particularly aggravated by movement of the big toe joint.
  • Pain that intensifies when walking barefoot or on hard surfaces.
  • Swelling on the bottom of the foot.

An X-ray can confirm if sesamoiditis is the cause of these symptoms.

Treatment of Sesamoiditis

The primary treatment for sesamoiditis is rest. Avoiding activities that cause pain will allow the affected area to heal. When walking is necessary, strapping the big toe to limit joint movement can be helpful.

Other treatment options include:

  • Anti-inflammatory medications to reduce pain and swelling.
  • Ice applied to the sole of the foot to decrease inflammation.
  • Cortisone injections may be recommended for more severe cases to provide additional pain relief and reduce inflammation.

While healing, it’s essential to wear comfortable shoes with cushioned soles to minimize pressure on the foot and protect the ball of the foot.

If you are experiencing signs of sesamoiditis, it’s important to schedule an appointment with your doctor to determine the best course of treatment for you.
