What Is Metatarsalgia?

Metatarsalgia is a general term for pain in the ball of the foot—the area across the metatarsal heads (the rounded ends of the five metatarsal bones that form the front of the foot). It is not a specific diagnosis but a symptom that can arise from multiple causes: overloading of one or more metatarsal heads, nerve irritation (Morton’s neuroma), stress fractures, capsulitis (inflammation of the joint capsule), fat pad atrophy, or systemic conditions like rheumatoid arthritis. Accurate diagnosis is essential because treatment differs substantially depending on the underlying cause.

The metatarsal heads bear approximately 40–50% of body weight during walking and up to 300% during running. Concentrated pressure at a single metatarsal head (due to a prominent or long metatarsal, a dropped metatarsal, high arch, tight Achilles tendon, or inappropriate footwear) leads to pain, callus formation, and eventually joint or nerve injury. The 2nd metatarsal—the longest metatarsal and the most fixed at its base—is most commonly overloaded in forefoot pathology.

Common Causes of Metatarsalgia

Mechanical Overload (Primary Metatarsalgia)

The most common cause is disproportionate loading of one or more metatarsal heads. A long or prominent 2nd metatarsal, hallux valgus (bunion) that transfers load to the 2nd metatarsal, high-arched feet (pes cavus) with elevated forefoot pressure, and loss of the plantar fat pad (which normally cushions the metatarsal heads) all concentrate pressure. Weight gain, high heels (which transfer weight forward onto the metatarsal heads), and prolonged standing or walking on hard surfaces exacerbate primary metatarsalgia. Treatment: metatarsal pads (placed just proximal to the painful metatarsal head to redistribute load), accommodative orthotics, cushioned low-heeled footwear, and activity modification.

Morton’s Neuroma

A thickened, irritated digital nerve (most commonly between the 3rd and 4th metatarsals) produces burning, tingling, and numbness in the adjacent toes alongside ball-of-foot pain. Patients often describe “stepping on a marble” or “sock bunching under the foot.” A positive Mulder’s click (palpable click when compressing the forefoot) is pathognomonic. Morton’s neuroma is the most important condition to distinguish from generic metatarsalgia because its treatment is different (primarily metatarsal pads, wide toe-box shoes, and corticosteroid injection; surgery when conservative measures fail).

Metatarsophalangeal (MTP) Capsulitis and Synovitis

Inflammation of the MTP joint capsule and synovium—most commonly at the 2nd MTP joint—produces deep joint-line pain, swelling, and pain with toe dorsiflexion. Plantar plate tears (disruption of the fibrocartilaginous plate at the base of the toe) are a more severe form that produces joint instability—the toe may cross over or drift toward an adjacent toe (crossover toe deformity). Early plantar plate tears respond to extension splinting (taping the toe in plantarflexion), metatarsal pads, and corticosteroid injection. Advanced or complete plantar plate tears with crossover deformity often require surgical repair.

Stress Fractures

Metatarsal stress fractures are a common cause of forefoot pain in runners, military recruits, and anyone with a sudden increase in high-impact activity. They produce point tenderness directly over a metatarsal bone (rather than diffuse ball-of-foot pain) and are confirmed with MRI. Stress fractures require a pause in high-impact activity—not metatarsal pads and continued running.

Treatment Approach

Treatment is matched to the specific diagnosis. For mechanical overload metatarsalgia: the most effective intervention is a metatarsal pad placed just behind (proximal to) the painful metatarsal head—not under it, which increases pressure. Custom orthotics with built-in metatarsal support are more durable than adhesive pads. Stiff-soled shoes with rocker-bottom reduce forefoot loading. NSAIDs reduce inflammation. For Morton’s neuroma: wide toe-box shoes to reduce interdigital compression, metatarsal pad, and corticosteroid injection (50–70% response rate); surgical neurectomy for refractory cases. For capsulitis: buddy taping, metatarsal pads, and corticosteroid injection for early stages; surgical plantar plate repair for complete tears with deformity.
