Pain directly under your big toe joint that gets worse every time you push off? That is the classic sign of a sesamoid injury — and it is one of the most commonly misdiagnosed sources of ball-of-foot pain we see at Family Foot & Leg Center. Whether you are a pickleball player in Naples, a runner in Fort Myers, or you simply spend long days on your feet, our board-certified podiatric surgeons diagnose and treat sesamoid injuries at 9 Southwest Florida locations with same-day appointments available.

The sesamoids are two small bones — the tibial and fibular sesamoids — embedded in the tendons beneath your big toe joint, working like the kneecap of your foot. Every step you take drives force through them. They protect the flexor hallucis longus tendon that pulls your big toe downward during walking, and they act as a fulcrum for the flexor hallucis brevis tendon that powers push-off. Because they absorb enormous repetitive load in such a small area, they are vulnerable to two distinct problems that feel nearly identical but require completely different treatment: sesamoiditis (inflammation of the bone lining) and sesamoid fracture (an actual break).
Pain focused directly under the big toe joint is the hallmark. It typically worsens with walking, running, jumping, wearing high heels, or rising onto the ball of your foot, and improves with rest. Some patients notice swelling or find they unconsciously walk on the outside of their foot to avoid the painful spot. Gradual onset after increased activity suggests sesamoiditis; sudden pain after a specific jump, sprint, or impact raises suspicion for fracture.
Our year-round active lifestyle is exactly the load profile sesamoids dislike: pickleball’s hard-court push-offs and lunges, golf’s rotational forefoot loading, beach running, tennis, and dance all concentrate force under the big toe joint. High-arched foot types, thinning of the natural fat pad with age, and unsupportive sandals — all common here in Naples, Fort Myers, and Sarasota — further raise the risk.
This distinction is the single most important step, because the treatments diverge sharply. At your first visit we localize the pain to the exact sesamoid with a focused exam, then obtain on-site digital X-rays including specialized axial sesamoid views. About 15% of people naturally have multipartite (multi-piece) sesamoids that mimic fractures on X-ray, so when the picture is unclear we compare views of your other foot or order an MRI. Treating a fracture as simple inflammation — or injecting cortisone into an undiagnosed fracture — can lead to nonunion and months of avoidable pain.
For sesamoiditis, we start with offloading: a dancer’s pad or custom orthotic engineered to shift pressure off the sesamoids while you keep walking, combined with activity modification, anti-inflammatory care, and calf stretching to reduce forefoot load. Stubborn cases respond well to a walking boot, shockwave therapy — available at our offices — or a precisely placed cortisone injection once fracture has been excluded. Most patients feel substantial relief within 4 to 6 weeks.
For sesamoid fractures, immobilization in a cast or boot for 6 to 8 weeks is the standard of care, followed by graduated return to weightbearing in a removable brace. Because the flexor tendon constantly pulls on the fracture fragments, these injuries have a genuinely high nonunion rate even with perfect care. When a fracture fails to heal and pain persists, our fellowship-trained surgeons perform sesamoidectomy — careful removal of the affected bone with soft tissue repair to preserve big toe strength and alignment.
In every case, we finish by correcting the root cause — gait mechanics, foot structure, footwear, training habits — so the problem does not come back. That is the difference between treating an X-ray and treating a patient.
Family Foot & Leg Center has served Southwest Florida since 2005 under the clinical direction of Dr. Kevin Lam, DPM, FACFAS, DABLES, DABPS — named among America’s Top Podiatrists and trained at Mount Sinai Medical Center and Jackson Memorial Health. With on-site digital X-ray, musculoskeletal ultrasound, shockwave therapy, in-house physical therapy, and 9 offices from Marco Island to Sarasota, you get a definitive diagnosis and a complete treatment plan without being bounced between facilities.
You cannot reliably tell at home — both hurt in the same spot. We differentiate them with focused examination and on-site X-rays (plus MRI when needed), usually at your first visit. The distinction is critical because the treatments are completely different.
Mild cases sometimes settle with rest and stiff-soled shoes, but continuing to load an inflamed sesamoid typically makes it chronic, and walking on an undiagnosed fracture risks nonunion. Early evaluation dramatically shortens recovery.
Accurate diagnosis followed by offloading with a dancer’s pad or custom orthotic, plus anti-inflammatory care. Resistant cases respond to shockwave therapy or a carefully placed cortisone injection after fracture is ruled out. Most patients improve within 4 to 6 weeks.
Rarely — over 90% of sesamoid problems resolve without surgery. Sesamoidectomy is reserved for nonunion fractures or truly chronic cases that have failed months of conservative care.
