Ball of Foot Pain:
What Causes It and When to See a Doctor
Pain beneath the ball of the foot is one of the most commonly misdiagnosed problems in podiatric practice. Five distinct conditions produce overlapping symptoms — and treating the wrong one will almost always make it worse.
Ball of foot pain — pain in the padded area just behind the toes — is among the most common complaints I evaluate in my clinic. It is also among the most commonly mismanaged. The five conditions that most frequently cause it — metatarsalgia, Morton’s neuroma, plantar plate tears, sesamoiditis, and metatarsal stress fractures — share enough overlap in location and character that they are routinely confused with one another, both by patients and by non-specialist providers. Getting the diagnosis right is not academic; it changes the treatment entirely. This guide will help you understand each condition, what it feels like, and when self-care is appropriate versus when you need to be evaluated.
The Anatomy of the Ball of the Foot
The ball of the foot is the region just proximal to the toes — the area you stand on when you rise to your tiptoes. Anatomically, this corresponds to the heads of the five metatarsal bones, which form the distal row of the midfoot and articulate with the proximal phalanges of the toes at the metatarsophalangeal (MTP) joints.
Between and beneath the metatarsal heads run the common digital nerves, the plantar plates (strong fibrocartilaginous ligaments that stabilize each MTP joint), the intrinsic foot muscles, the deep transverse metatarsal ligament, and the fat pad that cushions the metatarsal heads during weight-bearing. Beneath the first metatarsal head specifically sit two small sesamoid bones embedded within the flexor hallucis brevis tendon — these absorb tremendous load with each step and are vulnerable to their own distinct injuries.
When any of these structures is irritated, inflamed, torn, or fractured, the result is ball of foot pain. The challenge is that they are all located within centimeters of each other, and the pain they produce often feels similar from the patient’s perspective. The diagnostic clues lie in the precise location of maximum tenderness, the character of the pain (aching vs. burning vs. sharp), the factors that aggravate and relieve it, and the physical examination findings.
Using Location and Symptoms as Diagnostic Clues
Before reviewing each condition in detail, it is worth understanding how to use symptom location and character as a first filter — the same way I approach it when a patient walks into my office.
Diffuse aching and pressure pain beneath multiple metatarsal heads, worse in thin-soled or high-heeled shoes and after prolonged standing. Classic metatarsalgia. Often worsened by high arches, flat feet, or loss of the plantar fat pad.
Burning, electrical, or shooting pain radiating into the 3rd and 4th toes. Sensation of “walking on a pebble” or a “bunched-up sock.” Reproduced by squeezing the foot side-to-side. Classic Morton’s neuroma.
Sharp, localized pain directly beneath the 2nd (sometimes 3rd) metatarsal head, with progressive upward drift and crossing of the 2nd toe. Positive drawer test. Classic plantar plate tear.
Point-tender pain directly beneath the first metatarsal head, aggravated by dorsiflexion of the big toe and push-off. Pain when rising to tiptoe on the affected foot. Classic sesamoiditis or sesamoid fracture.
Progressively worsening, point-tender ache at a single metatarsal shaft (most often 2nd or 3rd), worsening with activity and improving with rest. No radiating symptoms, no toe deformity. Classic metatarsal stress fracture.
Metatarsalgia — The Most Common Cause
Metatarsalgia is a clinical descriptor rather than a specific diagnosis — it refers to pain and inflammation beneath one or more metatarsal heads, typically from excessive or uneven load on the forefoot. It is the most common cause of ball of foot pain and is frequently confused with the other conditions described in this guide, which is why it matters so much to exclude them first.
What Causes Metatarsalgia?
Elevated heels shift body weight forward onto the metatarsal heads, dramatically increasing forefoot pressure. Thin-soled shoes provide no cushioning to attenuate this load. Both are among the most common precipitating factors.
A high arch creates a rigid, poorly shock-absorbing foot that concentrates load on the metatarsal heads rather than distributing it along the entire plantar surface. Runners and hikers with cavus feet are particularly prone.
The natural cushioning beneath the metatarsal heads thins with age, often significantly after age 60. The protective padding is no longer there, and every step impacts the metatarsal heads directly. This is a common and underappreciated cause in older adults.
When the second metatarsal is longer than the first (Morton’s foot), it bears disproportionate load. This is a common anatomical variant that predisposes to both metatarsalgia and stress fracture of the second metatarsal.
Hammer toes, claw toes, and hallux valgus (bunion) alter forefoot biomechanics and concentrate pressure on specific metatarsal heads. Treating the underlying deformity is often necessary to resolve the metatarsalgia.
A sudden increase in running mileage, training intensity, or time on hard surfaces overwhelms the forefoot’s adaptive capacity. Common in recreational runners beginning training for a race.
Treatment
Switch to shoes with a wide, deep toe box, a cushioned forefoot, and a rocker sole if needed. Avoid heels above 1 inch. This is the single most impactful first-line intervention.
A correctly placed metatarsal pad (positioned proximal to — not under — the metatarsal heads) redistributes pressure and provides immediate relief. Placement matters; a pad placed incorrectly worsens pain.
For structural contributors such as high arches, fat pad atrophy, or second metatarsal excess length, a custom orthotic with metatarsal support and appropriate cushioning addresses the mechanical root cause.
Intrinsic foot muscle strengthening, toe flexor exercises, and calf flexibility improve forefoot load distribution and reduce metatarsal head pressure during gait.
For persistent inflammatory metatarsalgia that has not responded to conservative care, a targeted corticosteroid injection beneath the affected metatarsal head reduces inflammation and provides a window for rehabilitation.
Metatarsal osteotomy (shortening or elevating the metatarsal head surgically) is reserved for structural deformity-driven metatarsalgia that has failed comprehensive conservative care — typically over 6 months.
Morton’s Neuroma — The Burning, Electrical Pain
Morton’s neuroma is not a true tumor. It is a perineural fibrosis — a thickening of the tissue surrounding the common digital nerve as it passes between the metatarsal heads. The nerve is compressed by the metatarsal heads and the deep transverse metatarsal ligament above it, causing irritation, thickening, and eventually the characteristic burning and radiating pain. The third interspace (between the 3rd and 4th metatarsal heads) is involved in over 85% of cases.
The Burning, Electrical Pain Between the Toes
The classic symptom is a burning, electrical, or shooting sensation that radiates into the third and fourth toes. Patients commonly describe it as “walking on a pebble,” “feeling like my sock is bunched up,” or “an electric shock shooting into my toes.” The pain is typically absent at rest and provoked by weight-bearing in tight or narrow shoes. Removing the shoe and squeezing or massaging the ball of the foot briefly relieves symptoms — this is characteristic and diagnostically useful.
Diagnosis is clinical but can be confirmed with ultrasound (which shows the hypoechoic nerve mass between the metatarsal heads) or MRI. A diagnostic ultrasound-guided corticosteroid injection that fully reproduces and then eliminates the symptoms is both diagnostic and therapeutic.
Treatment Progression
Wide toe box shoes that do not compress the interspace. Avoid pointed-toe shoes and high heels. Many small neuromas respond to this alone within 4–6 weeks.
A metatarsal pad placed proximal to the neuroma separates the metatarsal heads and reduces nerve compression. Provides additional relief beyond footwear modification alone.
Ultrasound-guided corticosteroid injection into the affected interspace reduces perineural inflammation. Often provides months of relief; can be repeated 2–3 times before surgical consideration.
A series of 4–7 dilute alcohol injections gradually devitalizes the enlarged nerve tissue. Success rates of 60–80% are reported, with fewer risks than surgery. A useful intermediate step.
Surgical excision of the neuroma through a dorsal (top-of-foot) incision. Highly effective with excellent outcomes in appropriately selected patients. Permanent numbness in the affected web space is expected and well tolerated.
A metatarsal pad must be placed proximal to (behind) the metatarsal heads — not directly under them. When correctly placed, it elevates and spreads the metatarsal heads, reducing pressure on the nerve between them. When placed directly under the metatarsal heads, it increases the pressure the pad was supposed to reduce. Most over-the-counter pads come with diagrams that show incorrect placement. If your metatarsal pad is making symptoms worse, it is almost certainly in the wrong position.
Plantar Plate Tear — The Underdiagnosed Cause
The plantar plate is a thick, fibrocartilaginous structure on the plantar (bottom) surface of each metatarsophalangeal joint. It acts as the primary stabilizer of the MTP joint, preventing hyperextension of the toe and maintaining proper alignment. When it tears — typically from repetitive hyperextension of the toe during push-off — the stabilizing function is lost and the affected toe begins to drift upward and toward its neighbor.
Plantar plate tears most commonly affect the second MTP joint and are frequently misdiagnosed as metatarsalgia or Morton’s neuroma because of their similar location. The key distinguishing features are: pain that is specifically located beneath the MTP joint (not in the interspace), progressive upward drift of the toe, and a positive drawer test — in which the toe can be passively displaced upward (dorsally) relative to the metatarsal head with an abnormal degree of mobility.
Recognizing a Plantar Plate Tear
Treatment
Buddy-taping the affected toe in slight plantarflexion (downward) reduces tension on the plantar plate and can allow partial healing of minor tears. A rigid-soled shoe or stiff carbon fiber insert prevents the hyperextension that aggravates the tear.
A custom orthotic with a metatarsal bar and toe crest offloads the MTP joint and corrects the biomechanical pattern driving the injury. Essential for longer-term management of partial tears.
Complete tears and partial tears that fail conservative care require plantar plate repair — performed through a dorsal approach to the MTP joint. Suture anchors reattach the plate to the proximal phalanx. Recovery involves 4–6 weeks of protected weight-bearing.
A second toe that is progressively drifting upward and crossing over the great toe is a hallmark of plantar plate insufficiency. The longer this goes untreated, the more the MTP joint capsule stretches and the more the deformity becomes fixed — at which point surgical correction becomes more complex. A plantar plate tear caught early, when the deformity is still flexible and the toe can be manually corrected, has a much better prognosis than one treated after the joint has become rigid.
Sesamoiditis — Pain Under the Big Toe
The sesamoid bones are two small, pea-sized bones embedded within the flexor hallucis brevis tendon beneath the first metatarsal head. They function as pulleys for the tendon and absorb significant load during push-off. Sesamoiditis refers to inflammation of these bones and their surrounding structures; in more severe cases, one or both sesamoids may be fractured (either acutely or as a stress fracture).
Sesamoiditis is common in runners, dancers, and athletes who spend significant time on the balls of their feet. It is distinct from the other causes of ball of foot pain by its location: the pain is specifically beneath the first metatarsal head, not the lesser metatarsals, and is reliably reproduced by dorsiflexing (bending upward) the big toe while pressing on the sesamoid area.
Symptoms of Sesamoiditis
Both conditions cause pain in the same location, but a fracture requires a longer period of protected non-weight-bearing. X-rays can identify acute fractures but may miss stress fractures of the sesamoid. MRI is the gold standard for differentiating sesamoiditis (bone marrow edema without fracture line) from a stress fracture (fracture line present). Treatment for sesamoiditis includes offloading with a dancer’s pad (a donut-shaped pad that relieves pressure from the sesamoid area), stiff-soled footwear, and activity modification. Sesamoid fractures require 6–12 weeks of protected weight-bearing; non-healing fractures may ultimately require surgical excision of the affected sesamoid.
Metatarsal Stress Fracture — The Most Urgent Diagnosis
A metatarsal stress fracture is a fatigue fracture — a crack in the bone that develops from cumulative, repetitive loading that exceeds the bone’s capacity to remodel. Unlike an acute fracture from a single traumatic event, stress fractures develop gradually over days to weeks of increased activity. The second metatarsal is the most commonly affected, followed by the third. The fifth metatarsal (Jones fracture zone) carries special clinical significance because of its notoriously poor healing and higher risk of requiring surgical fixation.
The Condition That Cannot Wait for a Clinic Appointment
A metatarsal stress fracture must be identified early. Continued weight-bearing on an unrecognized stress fracture risks propagating the fracture to a complete break, which dramatically changes the prognosis and may convert a non-operative case to a surgical one. The diagnosis is frequently missed on plain X-rays during the first 2–3 weeks because the fracture line is too subtle or because the periosteal reaction has not yet formed. MRI is the gold standard for early diagnosis — it can identify bone marrow edema within 24–48 hours of injury.
The hallmark of a stress fracture is point tenderness — a single, precise spot on the metatarsal shaft that is exquisitely tender when pressed with a fingertip. This distinguishes it from metatarsalgia, which produces broader, more diffuse discomfort. The pain of a stress fracture worsens progressively with activity and improves with rest — often dramatically after a weekend off.
Risk Factors for Metatarsal Stress Fracture
The most common precipitant. A sudden increase in running mileage, training volume, or transition to harder surfaces overloads the bone before it can adapt. The “too much, too soon” training error.
Osteoporosis or osteopenia dramatically increases stress fracture risk. Post-menopausal women are particularly vulnerable. A first metatarsal stress fracture in a low-demand patient should prompt bone density evaluation.
The female athlete triad (low energy availability, menstrual dysfunction, low bone density) significantly increases stress fracture risk. Now recognized under the broader framework of Relative Energy Deficiency in Sport (RED-S).
A rigid cavus foot is a poor shock absorber and concentrates impact forces on specific metatarsal shafts, predisposing to stress fracture at those locations.
Worn-out running shoes with depleted cushioning, and hard training surfaces (concrete, asphalt), increase impact loading on the metatarsals.
Low Vitamin D and calcium impair bone remodeling capacity and increase fracture risk. Screening is worthwhile in patients with multiple or recurrent stress fractures.
A Jones fracture occurs at the base of the fifth metatarsal, in the watershed zone between two blood supplies — which is why it heals poorly. In recreational patients, non-operative treatment with a CAM boot is reasonable but requires close radiographic follow-up. In athletes who need to return to sport quickly, or in patients with delayed union, surgical fixation with an intramedullary screw provides significantly more reliable healing. If you have acute lateral foot pain after an ankle inversion and are told you have a “simple avulsion fracture” of the fifth metatarsal, ensure that your treating provider has confirmed the fracture is in the tuberosity (avulsion zone) and not the shaft (Jones zone) — the distinction changes management entirely.

When to See a Podiatrist
Some ball of foot pain responds to simple footwear changes and over-the-counter padding within a few weeks. The following situations warrant a professional evaluation rather than continued self-management:
Ball of foot pain that is correctly diagnosed responds well to treatment — but the wrong treatment can significantly worsen several of these conditions. A metatarsal pad placed in the wrong position increases neuroma symptoms. Continued running on a stress fracture risks a complete break. Untreated plantar plate tears progress to fixed toe deformity. An evaluation is the most efficient path to the right treatment.
Frequently Asked Questions
The key distinguishing feature is the character and location of the pain. Metatarsalgia produces a broad, diffuse, aching pressure beneath multiple metatarsal heads — like walking on pebbles distributed across the ball of the foot. Morton’s neuroma produces a more specific, burning or electrical sensation that radiates into the third and fourth toes, comes from the interspace between the metatarsal heads (not under them), and is distinctly relieved by removing the shoe and massaging the area. Squeezing the foot side-to-side while pressing on the 3rd–4th interspace (the Mulder test) reproduces the neuroma symptoms. If you are uncertain, an ultrasound can confirm the neuroma.
It depends on the cause. Mild metatarsalgia from a single footwear-related episode often resolves with footwear changes within a few weeks. Small Morton’s neuromas in their early stages may respond to conservative care without professional intervention. However, stress fractures will not heal with continued loading; plantar plate tears will not improve and will typically worsen without offloading; and sesamoid fractures require protection. Any pain that has lasted more than 2–3 weeks, is progressive, or is altering your gait should be evaluated rather than waited out.
No — and the majority of Morton’s neuromas do not. Approximately 80% of cases respond to conservative management when correctly diagnosed and appropriately treated: wide toe box footwear, metatarsal pad, and one to three corticosteroid injections. Sclerosing alcohol injection series are an effective intermediate option for cases that partially respond to corticosteroid injections but have not fully resolved. Surgery (neurectomy) is reserved for cases that have failed conservative care over 3–6 months, and it has an excellent success rate in appropriately selected patients.
Most metatarsal stress fractures heal with 4–6 weeks of protected weight-bearing in a CAM boot or surgical shoe, followed by a gradual return to activity over 2–4 additional weeks. The fifth metatarsal (Jones fracture zone) takes longer and requires closer radiographic follow-up because of its higher non-union risk. Return to full athletic activity typically takes 8–12 weeks from the time of diagnosis. Attempting to return too early is the most common cause of re-fracture.
It depends entirely on the diagnosis. Mild metatarsalgia — with appropriate footwear and a metatarsal pad — may allow modified running. But running on an undiagnosed stress fracture risks completing the fracture and converting a non-operative injury to a surgical one. Running with a plantar plate tear risks worsening the tear and accelerating toe deformity. Morton’s neuroma may be manageable at lower intensities with appropriate footwear, but will typically worsen with high-mileage running. The responsible answer is: get diagnosed first, then ask your podiatrist specifically about return to running.
A dancer’s pad is a donut-shaped offloading pad with a hole cut or molded in the center, placed so that the hole sits directly under the sesamoid bones. By surrounding the sesamoids with padding while leaving them unloaded, it shifts weight-bearing pressure away from the sesamoid area onto the surrounding tissue. It is the primary conservative treatment for sesamoiditis and sesamoid stress fractures. Custom dancer’s pads can be incorporated into orthotics for long-term management of sesamoid problems.
The Mulder test is performed by simultaneously squeezing the foot laterally (compressing the metatarsal heads together) while pressing directly upward on the plantar surface of the third–fourth interspace. A positive test reproduces the patient’s characteristic neuroma symptoms — the burning, radiating sensation — and may produce a palpable or audible click (Mulder’s click) as the enlarged nerve is displaced between the metatarsal heads. A positive Mulder test has moderate-to-high sensitivity and specificity for Morton’s neuroma. It is the key physical examination finding that differentiates neuroma from metatarsalgia in the clinical setting.
