Sesamoiditis: Big Toe Pain Under the Ball of the Foot &mdash relates to toe deformity — typically caused by imbalanced muscles + footwear. Most patients improve in depends on severity with conservative care. Same-week appointments in Howell + Bloomfield Hills: (810) 206-1402.
Medically reviewed by Dr. Tom Biernacki, DPM — Board-certified foot & ankle surgeon, 3,000+ surgeries performed. Updated April 2026 with current clinical evidence. This article reflects real practice experience from Balance Foot & Ankle Specialists in Howell and Bloomfield Hills, Michigan.
Quick Answer
Most foot and ankle problems respond to conservative care — proper footwear, supportive inserts, activity modification, and targeted stretching — within 4-8 weeks. Persistent pain beyond that window, or any symptom that prevents walking, warrants a podiatric evaluation to rule out fracture, tendon tear, or systemic cause.

Sesamoiditis: Big Toe Pain Under the Ball of the Foot
sesamoiditis treatment Michigan.– /wp:heading –>
Sesamoiditis is inflammation of the sesamoid bones — two small, pea-sized bones embedded within the flexor hallucis brevis tendon beneath the first metatarsophalangeal joint (big toe joint). These bones act as pulleys that amplify the power of the big toe during push-off. When they’re overloaded, the surrounding tendons and joint capsule become inflamed, producing a distinctive pain under the big toe that worsens with activity.
Anatomy: What Are the Sesamoid Bones?
Unlike most bones in the foot, the sesamoids are embedded within a tendon rather than connected by joints to adjacent bones. Every person has two sesamoid bones beneath the first metatarsal head — the medial (tibial) sesamoid and the lateral (fibular) sesamoid. They serve three functions: they absorb weight and impact forces beneath the big toe joint, reduce friction as the tendon glides, and increase the mechanical advantage of the flexor hallucis brevis muscle during toe push-off.
In some individuals, one or both sesamoids are bipartite — divided into two fragments from a congenital variant. This is normal, present in roughly 10–25% of people, and must not be misdiagnosed as a fracture. However, bipartite sesamoids are more susceptible to stress injury.
Causes of Sesamoiditis
Repetitive overloading — running (especially forefoot strikers), dancing, basketball, tennis; any activity with forceful push-off places high demand on the sesamoids
High arches (pes cavus) — concentrates weight on the forefoot and metatarsal heads
Thin-soled shoes — flat shoes without cushioning reduce the buffer between sesamoids and the ground
High-heeled shoes — shifts body weight forward onto the metatarsal heads
Ballet dancing (en pointe) — compresses the sesamoids maximally; sesamoiditis is extremely common in ballet dancers
Sudden activity increase — rapidly increasing mileage or switching from sedentary to active lifestyle
Direct trauma — a fall or jump landing directly onto the ball of the foot
Symptoms
Aching, sharp, or throbbing pain beneath the big toe joint, directly under the first metatarsal head
Pain that worsens with push-off, going up stairs, or wearing shoes with a hard sole
Tenderness directly on the sesamoid bones when pressed
Pain with forced extension (bending back) of the big toe
Swelling or bruising beneath the first metatarsal head in acute cases
Gradual onset over days to weeks (overuse) vs. sudden onset (fracture)
Morning stiffness of the big toe joint
Sesamoiditis vs. Sesamoid Stress Fracture: How to Tell the Difference
This distinction matters significantly for treatment. Both conditions cause pain under the big toe, but their management differs:
Onset: Sesamoiditis develops gradually; a fracture may have a more sudden onset, sometimes following a specific injury
X-ray: A bipartite sesamoid has smooth, rounded edges between fragments; a true fracture has irregular, jagged edges and does not match the contour of the other sesamoid
MRI or bone scan: Most sensitive for stress fracture; shows marrow edema within the sesamoid; diagnostic ultrasound useful for soft tissue assessment
Clinical test: Pain reproduced by passively extending the big toe (dorsiflexion) is more specific to sesamoiditis; a fracture may be tender along the full sesamoid length
Conservative Treatment
Activity Modification
Reducing or eliminating push-off-intensive activities is the cornerstone of initial treatment. Switch from running to swimming or cycling, which eliminates forefoot loading. This allows the acute inflammation to resolve. Most cases require 4–8 weeks of modified activity.
Sesamoid Offloading Padding
A J-shaped or donut-shaped felt or foam pad placed around (not over) the sesamoid bones transfers weight to the surrounding soft tissue. This is the single most effective immediate symptom-relief measure and can allow continued ambulation with dramatically reduced pain. A podiatrist can fabricate a custom pad and verify correct placement.
Stiff-Soled Shoe or Rocker Sole
Shoes with a stiff outsole or a rocker bottom reduce the bending moment at the first MTP joint during push-off, dramatically reducing sesamoid compression forces. A carbon fiber insert inside standard shoes provides similar stiffness. Avoid flexible shoes, flip-flops, and thin-soled shoes during active treatment.
Custom Orthotics
A custom orthotic with a first metatarsal head cutout (a small recess beneath the sesamoids) eliminates ground contact at the sesamoid area during each step. Combined with a metatarsal dome and arch support, this offloads the sesamoids while maintaining overall foot alignment. This is the most durable long-term mechanical solution for structural contributors to sesamoiditis.
MLS Laser Therapy
MLS laser therapy reduces periosteal inflammation around the sesamoids and promotes healing of the surrounding tendon and joint capsule. It’s particularly valuable for cases that haven’t responded to offloading alone and helps avoid cortisone injections. Typically 6–8 sessions produce significant improvement.
Cortisone Injection
An ultrasound-guided cortisone injection into the first MTP joint or adjacent bursa reduces acute inflammation rapidly. Use is limited — repeated cortisone injections around the sesamoids risk fat pad atrophy and tendon weakening. One injection in combination with other interventions is appropriate for severe acute symptoms.
Immobilization
For stress fractures or very severe sesamoiditis unresponsive to padding and activity modification, a short walking boot for 6–8 weeks with complete offloading of the forefoot is required. Non-weight-bearing may be indicated for confirmed sesamoid stress fractures to prevent progression to complete fracture or avascular necrosis.
When Is Surgery Needed?
Surgery is reserved for cases that fail 6–12 months of conservative care. Options include:
Sesamoidectomy — surgical removal of one (rarely both) sesamoid bones; very effective for refractory pain; risks include toe weakness, hallux valgus (bunion) development after medial sesamoid removal, and hallux varus after lateral removal
Bone grafting — for sesamoid stress fracture with non-union; attempts to heal the fracture while preserving the sesamoid
Shaving — smoothing of an irregular or arthritic sesamoid surface without complete removal
Recovery Timeline
Sesamoiditis has one of the slowest healing timelines of any foot overuse injury due to the sesamoids’ poor blood supply (similar to the navicular bone). Realistic expectations:
Mild sesamoiditis: 4–6 weeks with proper offloading, modified activity
Moderate sesamoiditis: 3–4 months
Sesamoid stress fracture: 3–6 months in walking boot; up to 12 months in dancers or high-level athletes
Athletes must resist the urge to return to full training prematurely. Re-injury resets the healing clock completely and risks fracture progression or avascular necrosis.
class=”mfd-patient-scenario” id=”more-sesamoiditis-guides-from-dr-tom-hallux-sesamo”>In Our Clinic: What We See
Clinical perspective from Dr. Tom Biernacki, DPM — Balance Foot & Ankle, Howell & Bloomfield Hills, MI:
In our Balance Foot & Ankle clinic, sesamoiditis patients are usually dancers, runners, or women who have spent significant time in heels. They describe pain directly UNDER the big toe joint — not at the joint (that’s hallux rigidus) — which worsens with push-off. On exam we palpate each sesamoid separately (tibial and fibular) and assess for sensitivity. We always get X-rays to look for sesamoid fracture or bipartite sesamoid (a normal variant). Treatment uses a dancer’s pad to offload the sesamoid, stiff-soled footwear to reduce push-off stress, and activity modification.
class=”mfd-differential” id=”more-sesamoiditis-guides-from-dr-tom-hallux-sesamo”>Differential Diagnosis: What Else Could It Be?
Not every case of sesamoiditis is straightforward. In our clinic we routinely rule out three look-alike conditions before confirming the diagnosis. If your symptoms don’t match the classic presentation, one of these may explain the pain — which is why physical exam matters more than self-diagnosis.
Condition
How It Differs
Sesamoid stress fracture
Acute or gradually worsening sharp pain, tender directly over one sesamoid, positive findings on MRI.
Hallux rigidus
Stiff, painful big toe joint with limited dorsiflexion — pain is AT the joint, not UNDER the ball.
Turf toe (plantar plate injury)
Acute hyperextension mechanism, diffuse swelling of the 1st MTP, positive 1st MTP drawer test.

Bring your current shoes and a short list of symptoms and we’ll build you a treatment plan in one visit.
How do I know if I have sesamoiditis or a sesamoid fracture?
Both cause pain under the big toe, but a fracture typically has a more sudden onset, more severe pain with any weight-bearing, and visible changes on X-ray (irregular edges at the sesamoid). Sesamoiditis develops gradually and is more localized to activity-related pain. An MRI is the most definitive test — it shows bone marrow edema within a fractured sesamoid but not in simple tendinitis. A podiatrist can guide the correct imaging workup.
Can sesamoiditis heal without surgery?
The vast majority of sesamoiditis cases (including many stress fractures) heal without surgery with adequate offloading, modified footwear, and patience. Surgery (sesamoidectomy) is typically a last resort after 6–12 months of failed conservative care. The challenge is that most patients return to activity too soon, prolonging the healing process. Strict adherence to offloading protocols significantly improves non-surgical outcomes.
The right footwear can make or break your recovery. Dr. Tom’s complete guide to the best shoes for plantar fasciitis, flat feet, neuropathy, bunions & more — with clinical picks for every foot type.
The ideal shoe for sesamoiditis has a stiff or rocker sole (to reduce push-off bending forces), a wide toe box (to avoid compression of the first MTP joint), adequate forefoot cushioning, and a low to moderate heel (1–1.5 inches). Running shoes with maximum forefoot cushioning (HOKA Bondi, Brooks Glycerin) and a rocker profile are often recommended. Avoid completely flat shoes, thin-soled shoes, high heels, and ballet flats during treatment.
Can I run with sesamoiditis?
Running during active sesamoiditis significantly prolongs healing and risks fracture. During the acute phase (first 4–8 weeks of treatment), running should be eliminated. Cycling and swimming are appropriate substitutes. Return to running is appropriate when pain has been absent for 2+ consecutive weeks with normal walking, and ideally verified by a follow-up ultrasound or MRI showing resolved inflammation.
Pain under the big toe that isn’t getting better with rest deserves a proper evaluation. Balance Foot & Ankle in Howell and Bloomfield Hills, Michigan offers on-site X-ray, diagnostic ultrasound, MLS laser therapy, and custom orthotic fabrication.

Sesamoiditis is inflammation of the two pea-sized sesamoid bones embedded in the flexor tendons beneath the first metatarsal head (big toe joint). The sesamoids act as a pulley for the flexor hallucis brevis, absorbing significant load with every push-off. Causes include high-impact activity (running, dancing, jumping), high-arched feet that concentrate load under the first ray, thin-soled footwear, and sudden activity increases. It’s most common in runners and dancers in their 20s–40s.
What does sesamoiditis feel like?
A dull to sharp ache directly under the big toe joint — specifically at the ball of the foot, not at the toe knuckle. Pain worsens with push-off, going up on tiptoe, and wearing heels. Walking downstairs or on uneven ground is often uncomfortable. Unlike Morton’s neuroma, there’s no radiating pain into the toes. Unlike plantar fasciitis, the pain is not worst with first morning steps — it builds with activity and improves with rest.
How long does sesamoiditis take to heal?
Mild cases: 4–8 weeks with proper offloading. Moderate cases: 3–4 months. Severe sesamoiditis with bone edema on MRI: 4–6 months, sometimes longer. Sesamoid fractures (which can occur alongside sesamoiditis) require a walking boot for 6–8 weeks and may need surgical removal if they don’t heal. The most important factor is consistent load reduction during the healing phase — patients who continue high-impact activity through sesamoiditis triple their recovery time.
What is a dancer’s pad and does it help sesamoiditis?
A dancer’s pad (also called a J-pad or sesamoid offloading pad) is a felt or foam pad with a cutout beneath the sesamoid bones. It redirects load to the surrounding metatarsal head while leaving the painful area pressure-free. It’s one of the most effective short-term interventions for sesamoiditis — most patients report significant pain reduction within 1–2 weeks of correct placement. We fabricate these in-office. They’re more effective than standard metatarsal pads for first-ray pathology.
Do I need a walking boot for sesamoiditis?
Moderate-to-severe cases benefit significantly from a short period (2–4 weeks) in a walking boot to completely offload the sesamoids. If pain is present with normal walking or the MRI shows bone edema (stress reaction), a boot is typically recommended. Mild cases can often be managed with a dancer’s pad alone. A boot is not an admission that surgery is coming — it’s an aggressive conservative treatment to reset the inflammation and give the bone a chance to recover.
What are the best insoles for sesamoiditis?
Insoles with a first-ray cutout or dancers’ modification are most effective — standard arch support doesn’t help sesamoiditis because the problem is under the first metatarsal, not the arch. Custom orthotics with a first-ray cutout are the gold standard; quality OTC options include the Powerstep Pinnacle with added padding modified to offload the first ray. In our clinic, we modify OTC insoles in-office for sesamoiditis patients who don’t yet need custom fabrication.
Can sesamoiditis lead to surgery?
In fewer than 10% of cases. Surgery (sesamoidectomy — removal of the affected sesamoid) is considered after 6–12 months of failed conservative management, or when there’s a displaced fracture that won’t heal. Results are generally good — 80–85% of patients return to full activity. However, removing the tibial (medial) sesamoid can cause hallux valgus (bunion) as a complication, so indications are carefully considered. We exhaust all conservative options before recommending sesamoidectomy.
Can I run with sesamoiditis?
Running through active sesamoiditis risks stress fracture and significantly delays recovery. During the acute phase (pain >3/10 with walking), rest from impact completely. Swimming and cycling are excellent alternatives. As symptoms improve, a gradual return begins — short runs on soft surfaces with a dancer’s pad, increasing distance by no more than 10% weekly. Full return to unrestricted running typically takes 3–6 months. Runners who skip the rest phase reliably end up in a boot for 3 months instead.
Is a sesamoid stress fracture the same as sesamoiditis?
No — but they coexist frequently and present identically. Sesamoiditis is soft tissue inflammation; a stress fracture is an actual crack in the bone from repetitive overload. X-ray often can’t distinguish them from a bipartite sesamoid (a naturally two-part bone present in 10–30% of people). MRI is the definitive diagnostic tool — bone marrow edema on MRI confirms stress reaction or fracture. This distinction matters because stress fractures require more aggressive rest and longer protection.
What shoes should I wear for sesamoiditis?
Stiff-soled shoes that minimize first MTP joint flexion are most protective — a stiff rocker-bottom sole prevents the push-off motion that loads the sesamoids. Hoka Bondi and similar maximally cushioned rocker designs are excellent. Avoid flexible, thin-soled shoes entirely. Heels of any height are contraindicated because they increase forefoot load. For daily use, a stiff-soled casual shoe with an added dancer’s pad provides good protection.
