Metatarsalgia: Understanding Ball-of-Foot Pain

What Is Metatarsalgia?

Metatarsalgia is a general term for pain in the ball of the foot (the metatarsal heads, the bony region just behind the toes). It is a symptom rather than a specific diagnosis, and identifying the underlying cause is essential for appropriate treatment.

Common Causes

• Overload — excessive pressure under specific metatarsal heads due to foot shape, footwear, or activity level
• Morton’s neuroma — thickening of the nerve between the 3rd and 4th toes, causing burning, shooting pain
• Metatarsophalangeal (MTP) joint instability — often follows hammertoe deformity or inflammatory arthritis
• Stress fracture of a metatarsal — particularly in runners and military recruits
• Hallux valgus (bunion) — transfer of load to the lesser metatarsals
• Freiberg’s disease — avascular necrosis of the 2nd metatarsal head

Symptoms

• Pain, burning or aching in the ball of the foot
• Pain worse with standing and walking, relieved with rest
• Feeling like there is a stone in the shoe
• Numbness or tingling between the toes (Morton’s neuroma)

Diagnosis

Diagnosis relies on careful clinical assessment, identifying the specific anatomical location of tenderness. Ultrasound is valuable for identifying Morton’s neuroma and assessing plantar plate integrity. X-rays are obtained to rule out stress fracture, osteonecrosis and arthritis.

Treatment

Conservative treatment is effective for most causes of metatarsalgia: offloading metatarsal pads or custom orthotics, appropriate footwear (wide toe box, cushioned sole), activity modification, and physiotherapy.

For Morton’s neuroma, an ultrasound-guided corticosteroid injection frequently provides long-lasting relief. Surgical excision of the neuroma is reserved for cases that fail injection therapy.

Surgical treatment of other causes (correcting hammertoe deformity, metatarsal osteotomy to equalise loading) is available for patients not responding to conservative management.
