Sesamoiditis: Pain Beneath the Big-Toe Joint
Two pea-sized sesamoid bones sit under the big-toe joint and take huge load when you push off. Sesamoiditis is the inflammation of these bones and their tendons, common in runners and dancers.
What sesamoiditis is
The sesamoids are small bones embedded in the tendon beneath the big toe, acting like a pulley to boost push-off power. Overload inflames the surrounding tissue (sesamoiditis), and repeated stress can cause a fracture, so distinguishing the two matters.
Symptoms
- A dull, persistent ache under the big-toe joint
- Pain that worsens with push-off, running or wearing heels
- Swelling and tenderness directly under the joint
- Difficulty bending the big toe
Causes
Activities with repeated forefoot loading — running, dancing, basketball — plus high arches, thin-soled or high-heeled shoes, and a sudden increase in training are typical triggers.
Treatment and offloading
Rest from aggravating activity, ice, cushioned low-heeled shoes, and a 'dancer's pad' cut to offload the sesamoids are first-line. Stiff-soled shoes or a rocker sole reduce big-toe bending. Taping the toe in a slightly down position can rest the area. Recovery often takes several weeks; the Mayo Clinic notes that persistent forefoot pain should be imaged to exclude a fracture.
When to seek care
See a podiatrist if pain is severe, does not settle with offloading, or follows a specific injury, as a sesamoid fracture or stress fracture may need protected immobilisation.
Frequently asked questions
- How long does sesamoiditis take to heal?
- Mild cases settle in a few weeks with offloading; more severe or fractured sesamoids can take months.
- What shoes are best for sesamoiditis?
- Cushioned, stiff-soled or rocker-bottom shoes with a low heel, plus a dancer's pad to relieve the joint.
