What Is Sesamoiditis?

 

What Is Sesamoiditis?

Sesamoiditis is a type of tendon inflammation (tendonitis) that affects the tendons surrounding the sesamoid bones in the ball of the foot.

The two small sesamoid bones sit beneath the big toe joint and act like a pulley system. They help:

  • Absorb weight-bearing pressure

  • Improve leverage during push-off

  • Support natural walking mechanics

Because these bones are embedded within tendons (rather than directly attached to other bones), they move with every step. Activities that repeatedly load the ball of the foot can overstress this structure, leading to pain and inflammation.

What Causes Sesamoiditis?

Sesamoiditis is most commonly caused by overuse.

High-risk groups include:

  • Runners

  • Dancers

  • Athletes

  • People who wear high heels frequently

  • Individuals with high arches or flat feet

  • People who overpronate (inward foot roll)

Repeated pressure on the ball of the foot increases strain on the sesamoid bones and surrounding tendons.

In some cases, sesamoiditis may also be associated with gout or inflammatory conditions.

Symptoms of Sesamoiditis

Common symptoms include:

  • Pain in the ball of the foot (under the big toe)

  • Pain that worsens with activity

  • Swelling or tenderness

  • Difficulty bending the big toe

  • Discomfort when wearing tight or narrow shoes

Pain may develop gradually and intensify over time, especially with continued activity.

How Is Sesamoiditis Diagnosed?

A healthcare provider will typically:

  • Ask about activity level and onset of pain

  • Perform a physical examination

  • Move the big toe to evaluate mobility

  • Apply pressure to identify tenderness

In some cases, imaging tests may be recommended to rule out other conditions such as:

  • Stress fractures

  • Turf toe (soft tissue injury)

  • Hallux rigidus (arthritis of the big toe joint)

Diagnostic tools may include X-rays, MRI scans, CT scans, bone scans, or ultrasound imaging.

Treatment for Sesamoiditis

Most cases of sesamoiditis can be treated without surgery.

Conservative Treatment Options

  • Rest and reduced activity

  • Ice therapy to reduce inflammation

  • Anti-inflammatory medications

  • Elevation after activity

  • Taping or cushioning pads

Reducing pressure on the forefoot is essential during recovery.

Supportive Footwear & Orthotics

Proper footwear is one of the most important components of treatment and prevention.

Supportive shoes help:

  • Redistribute pressure away from the ball of the foot

  • Cushion impact during walking

  • Improve alignment

  • Reduce strain on the big toe joint

DrLuigi® medical footwear is designed to provide structured support, cushioning, and pressure relief — helping reduce stress on the forefoot and improve everyday comfort.

Avoid:

  • High heels

  • Narrow toe boxes

  • Thin, flat soles

  • Worn-out shoes

If you stand for long periods or have high arches or flat feet, structured and supportive footwear becomes even more important.

How to Reduce Your Risk of Sesamoiditis

Prevention strategies include:

  • Wearing comfortable, supportive shoes

  • Avoiding excessive high-impact activity

  • Gradually increasing exercise intensity

  • Stretching the foot and calf muscles

  • Resting after strenuous activity

If you know you have strained your feet, follow activity with rest, ice, and elevation to reduce inflammation.

Choosing properly structured footwear like DrLuigi® supportive shoes helps relieve pressure on the big toe joint and supports healthier foot mechanics.

When to See a Doctor

If ball-of-foot pain persists, worsens, or interferes with daily activity, consult a healthcare professional for proper diagnosis.

With early treatment, supportive care, and appropriate footwear, most people recover fully and return to normal activity.
