What is Sesamoiditis?
Sesamoiditis is inflammation of the small sesamoid bones found beneath the big toe joint. These two tiny bones act like pulleys for tendons, helping the big toe move properly and absorb weight while walking or running. When the tendons surrounding these bones become irritated or inflamed, it leads to pain and swelling, a condition known as sesamoiditis.
What causes sesamoiditis?
Sesamoiditis is often caused by repetitive pressure or overuse of the forefoot. Activities that involve running, jumping, dancing, or wearing high heels can increase stress on the ball of the foot. It may also develop from trauma, tight calf muscles, or improper footwear that puts extra pressure on the big toe joint.
What are the symptoms?
Common symptoms include:
- Pain in the ball of the foot, just beneath the big toe
- Swelling or bruising around the joint
- Difficulty bending or straightening the big toe
- Pain that worsens with walking or running
How is sesamoiditis diagnosed?
Our podiatrist will evaluate your symptoms, review your activity level, and examine your foot. X-rays or other imaging tests may be used to rule out a fracture or other foot conditions that can cause similar pain.
How is sesamoiditis treated?
Treatment focuses on relieving pressure and reducing inflammation. Our podiatrist may recommend:
- Resting and avoiding high-impact activities
- Icing the affected area
- Wearing cushioned or supportive shoes
- Using custom orthotics or padding to reduce stress on the sesamoid bones
- Anti-inflammatory medications, if necessary
In more severe cases, immobilization or physical therapy may be recommended. Surgery is rarely needed but may be an option for chronic cases that don't respond to conservative treatment.
How can I prevent sesamoiditis?
To help prevent sesamoiditis, wear shoes that fit properly and provide good cushioning under the ball of the foot. Gradually increase activity levels. especially if you run or dance, and stretch your calves and toes regularly to keep the forefoot flexible.
When should I see a podiatrist?
If you experience persistent pain under your big toe that doesn't improve with rest or shoe changes, schedule an appointment today. Early treatment can prevent the condition from worsening and help you return to your normal activities pain-free.
