Weil Osteotomy (metatarsal shortening)	Adjunct in complex cases	Yes (for dropped metatarsal; elevates head)	Metatarsal shortening also decompresses interdigital nerve in crossover cases

Ball-of-foot pain is one of the most common complaints we evaluate at Balance Foot & Ankle, and the two conditions most often confused are Morton’s neuroma and metatarsalgia. Patients frequently come in having self-diagnosed the wrong condition — spending months on treatments that didn’t work because the diagnosis was off. The distinction matters: a neuroma needs nerve-specific treatment (corticosteroid injection, alcohol sclerosing, or neurectomy), while metatarsalgia responds to load redistribution. This guide gives you the clinical decision framework to understand which one you likely have, how both are diagnosed, and what the evidence actually says about treatment.

What Is Morton’s Neuroma

Despite the name, Morton’s neuroma is not actually a tumor — it is a benign enlargement and perineural fibrosis of the common digital nerve where it passes between the metatarsal heads in the ball of the foot. The 3rd web space (between the 3rd and 4th metatarsals) is affected most often, accounting for approximately 65% of cases. The 2nd web space is next most common. Multiple neuromas or bilateral neuromas occur in approximately 10-15% of cases.

The mechanism is chronic compression and traction: the transverse metatarsal ligament sits just above the nerve, and in narrow footwear, the metatarsal heads compress the nerve against this ligament with every step. Over time, this causes reactive thickening, fibrous tissue deposition, and nerve degeneration. The result is the characteristic burning, shooting, or electric pain that shoots into the affected toes — often described as “walking on a marble” or “a pebble in the shoe.” In our clinic, it is the nerve quality of the pain — shooting, burning, electric, with toe numbness — that reliably distinguishes neuroma from metatarsalgia on history alone.

What Is Metatarsalgia

Metatarsalgia is not a single diagnosis — it is a clinical syndrome describing pain and inflammation at or under the metatarsal heads (the “knuckles” of the foot that form the ball of the foot). The 2nd metatarsal head is the most commonly affected because it bears the highest relative load during the propulsive phase of gait, particularly in patients with hallux valgus (bunion) that transfers load laterally.

The causes of metatarsalgia are numerous and often overlap. Common drivers include: plantar fat pad atrophy (especially in older adults), tight gastrocnemius producing forefoot overload, long 2nd metatarsal (Morton’s foot — not to be confused with Morton’s neuroma), hammertoe deformity shifting load to the metatarsal heads, high-impact athletic activity without adequate cushioning, and inflammatory arthritis (rheumatoid arthritis frequently starts at the 2nd MTP joint with a clinical picture that exactly mimics metatarsalgia).

How Morton’s Neuroma and Metatarsalgia Are Diagnosed

Accurate diagnosis requires a combination of history, physical examination, and targeted imaging — not just the location of pain. Both conditions cause pain in the ball of the foot, and they can coexist in the same foot.

Physical Examination Tests

• Mulder’s click test (neuroma): The examiner squeezes the forefoot from side to side while pressing upward in the web space. A palpable or audible “click” with reproduction of the patient’s burning pain is highly specific for Morton’s neuroma. Sensitivity is 61-98% in published series.
• Web space compression (neuroma): Direct firm pressure in the 3rd web space (between the metatarsal heads) reproducing burning or electric pain into the toes is positive for neuroma.
• Metatarsal head palpation (metatarsalgia): Direct plantar pressure on the metatarsal head(s) reproducing a deep, aching, bruised-type pain without toe radiation indicates metatarsalgia. The 2nd metatarsal head is the most common location.
• MTP stress test (2nd MTP synovitis): Dorsal-plantar stress of the 2nd MTP joint producing pain or instability indicates MTP synovitis or capsular laxity — a specific form of metatarsalgia requiring its own treatment approach.

Imaging

• Ultrasound: The first-line imaging for Morton’s neuroma — faster, cheaper, and more dynamic than MRI. A hypoechoic lesion >5mm in the intermetatarsal space is diagnostic. Ultrasound also allows real-time guided corticosteroid injection for both diagnosis and treatment in one session. We routinely use ultrasound-guided injection at Balance Foot & Ankle.
• MRI: More sensitive than ultrasound for small neuromas and better for evaluating adjacent structures (MTP synovitis, stress fracture, plantar plate tear) that can mimic or coexist with neuroma. Used when ultrasound is inconclusive or when surgical planning requires precise localization.
• Weight-bearing X-rays: Essential for metatarsalgia to assess metatarsal formula (relative lengths), hallux valgus angle, sesamoid position, and joint space narrowing suggesting arthritis.

Treatment: Morton’s Neuroma

Treatment of Morton’s neuroma follows a stepwise protocol from conservative to interventional. In our practice, approximately 70% of patients achieve satisfactory relief without surgery when they consistently follow the conservative protocol and follow through with corticosteroid injection series.

Conservative: Footwear and Orthotics

Wider-toed shoes are the single most effective conservative intervention — they immediately reduce the compression of the metatarsal heads against the nerve. Shoes should be at least 1cm wider than the widest part of your foot at the forefoot. A metatarsal pad placed just proximal to (behind) the metatarsal heads spreads the metatarsals apart and decompresses the nerve. Placement matters: if the pad is under the metatarsal head rather than behind it, it worsens symptoms. We often have patients test placement in-office with a removable pad before prescribing custom orthotics.

Corticosteroid Injection

Ultrasound-guided corticosteroid injection into the web space is the most effective non-surgical treatment, with 60-80% short-term relief in published series. We perform these under ultrasound guidance at Balance Foot & Ankle to ensure accurate placement. A series of 2-3 injections at 4-6 week intervals is typically prescribed. Corticosteroid injection does not eliminate the neuroma — it reduces the perineural inflammation that causes symptoms. If symptoms recur, alcohol sclerosing series is the next step.

Alcohol Sclerosing Injections

A series of 4-7 injections of dilute ethyl alcohol (4%) under ultrasound guidance chemically destroys the neuroma tissue without surgery. Published series show 84-89% patient satisfaction with long-term follow-up. This is an excellent option for patients who want to avoid surgery but have not had durable relief from corticosteroids. It requires multiple visits over 6-10 weeks.

Neurectomy (Surgery)

Surgical excision of the neuroma (neurectomy) is reserved for cases that fail 6-12 months of conservative care including injection series. The procedure is performed under local or regional anesthesia as an outpatient. Success rates are 75-85% in published series. The main risk is the inevitable development of a small “stump neuroma” at the nerve transection site — for most patients this is asymptomatic, but in a subset it can be as painful as the original neuroma. We prefer a dorsal (top of foot) surgical approach over plantar to avoid scar formation on the weight-bearing surface.

Treatment: Metatarsalgia

Metatarsalgia treatment targets the underlying cause of metatarsal head overload. Because metatarsalgia is a syndrome rather than a single diagnosis, treatment must be individualized based on the driver.

• Metatarsal pads and cushioning: A well-placed metatarsal pad redistributes load from the metatarsal heads to the metatarsal shafts, providing immediate relief for most patients. Cushioned insoles with forefoot padding add shock absorption for athletes and hard-floor workers.
• Custom orthotics: For recurrent or severe metatarsalgia, custom orthotics address the specific foot architecture driving overload — whether it is a long 2nd metatarsal, equinus contracture forcing forefoot loading, or hypermobile first ray transferring load to the 2nd.
• Physical therapy: Intrinsic foot muscle strengthening (toe flexor exercises, towel scrunching, short foot exercises) restores the natural metatarsal arch and reduces joint capsule stress. Gastrocnemius stretching is essential when equinus is contributing.
• Activity modification: Runners with metatarsalgia often need to reduce mileage temporarily, switch to softer surfaces, and avoid barefoot or minimalist footwear until symptoms resolve.
• MTP joint injection: For 2nd MTP synovitis and capsular laxity, a corticosteroid injection into the joint reduces inflammation and allows the capsule to stabilize. Chronic capsular laxity with “floppy toe” may require MTP stabilization surgery (plantar plate repair).
• Surgery for structural deformity: When metatarsalgia is driven by a long 2nd metatarsal or hallux valgus, surgical correction of the underlying deformity (metatarsal osteotomy, bunion surgery) may be necessary for lasting relief.

The Most Common Mistake We See

The most common mistake is treating Morton’s neuroma with thick cushioned insoles alone. Cushioned insoles address the metatarsal head pressure (metatarsalgia), but they do not address the lateral compression of the metatarsal heads that pinches the nerve in neuroma. A thick insole without a metatarsal dome to spread the metatarsals apart actually makes neuroma worse by narrowing the forefoot compartment inside the shoe. The critical element for neuroma is a metatarsal dome or pad placed proximal to the metatarsal heads — not under them. This specific placement is counterintuitive and is consistently wrong when patients self-treat before seeing us.

Frequently Asked Questions

Can Morton’s neuroma go away on its own?

Small early-stage neuromas may become asymptomatic with footwear changes alone. However, established neuromas with significant perineural fibrosis rarely resolve spontaneously. The neuroma tissue itself does not disappear — the goal of conservative treatment is to reduce the inflammation and compression that makes it painful, not to eliminate the physical thickening. Without treatment, most neuromas progressively worsen over time with increasing footwear restriction.

What does metatarsalgia feel like?

Metatarsalgia typically feels like a deep aching, bruised, or tender sensation under the ball of the foot — often described as “walking on pebbles” or “a bruise that won’t go away.” It is worse with impact activities (running, jumping, hard floors) and better with rest and cushioned footwear. Unlike Morton’s neuroma, there is no shooting or burning pain into the toes and no numbness.

How do I know if I have Morton’s neuroma vs metatarsalgia?

If your forefoot pain is burning, shooting, or electric with numbness in specific toes (usually 3rd and 4th), Morton’s neuroma is more likely. If your pain is an aching, diffuse bruised feeling under the ball of the foot with no toe symptoms, metatarsalgia is more likely. A podiatrist can confirm the diagnosis with the Mulder’s click test and ultrasound — this clinical distinction directly determines treatment, so an accurate diagnosis is important.

When should I see a podiatrist for ball of foot pain?

See a podiatrist if forefoot pain persists despite wider shoes and cushioned insoles, if you have numbness or burning in your toes, if pain is severe or limiting your activity, or if you have diabetes with new foot pain. At Balance Foot & Ankle we offer same-day appointments in Howell and Bloomfield Hills — call (810) 206-1402.

Does insurance cover Morton’s neuroma treatment?

Yes, most insurance plans including Medicare cover evaluation, cortisone injections, and surgery for Morton’s neuroma. Custom orthotics may require a co-pay or separate authorization. Alcohol sclerosing injections coverage varies by insurer. Call Balance Foot & Ankle at (810) 206-1402 to verify your specific coverage.

Frequently Asked Questions

What does metatarsalgia feel like?

Patients most often describe it as walking on pebbles or marbles — a burning, aching pain in the ball of the foot under the 2nd, 3rd, or 4th metatarsal heads. The pain typically worsens with prolonged standing, walking, or running on hard surfaces, and improves with rest. Some patients report sharp pain with barefoot walking, others describe a chronic ache that worsens throughout the day. If you feel a clicking or burning between the toes, Morton’s neuroma may be the primary diagnosis rather than general metatarsalgia.

What causes metatarsalgia?

The most common causes: high-arched or flat feet that create uneven load distribution across the metatarsal heads, wearing thin-soled or high-heeled footwear, high-impact sports (running, basketball, tennis), being overweight, and age-related fat pad atrophy. Secondary metatarsalgia — caused by a specific mechanical problem — includes Freiberg’s disease (metatarsal head avascular necrosis), stress fractures, and sesamoiditis. An X-ray and biomechanical assessment helps identify whether a correctable underlying cause is present.

What’s the difference between metatarsalgia and Morton’s neuroma?

Metatarsalgia is diffuse pain at the metatarsal heads from overload. Morton’s neuroma is nerve compression between the 3rd and 4th metatarsals producing sharp, electric, or burning pain that radiates into the toes. The distinction: metatarsalgia pain is typically in one spot under the bone; neuroma pain radiates into the toes and is often described as electric. Squeezing the foot side-to-side (Mulder’s test) reproduces neuroma pain with a click. Both can coexist.

Do metatarsal pads help metatarsalgia?

Yes — when placed correctly. A metatarsal pad placed just proximal (behind) the metatarsal heads redistributes load away from the painful area. Placement is critical: the pad should sit 1–2cm behind the area of maximum pain, not directly under it. Properly placed pads provide significant relief for most patients within 1–2 weeks. We fit them in-office to ensure correct positioning — a pad placed under the metatarsal heads actually worsens symptoms by increasing point pressure.

What shoes are best for metatarsalgia?

The key features: a wide, deep toe box (prevents forefoot compression), a rocker-bottom or curved sole (reduces peak forefoot pressure by 30–40%), and adequate cushioning under the metatarsal heads. Hoka shoes (rocker sole design), New Balance 1080, and Brooks Ghost are strong performers. Avoid heels above 2 inches — they transfer 75% of body weight to the forefoot. Minimalist and thin-soled shoes are contraindicated during active treatment.

Can I run with metatarsalgia?

Often yes, with modification. Reduce mileage and intensity, switch to a softer surface (grass or track vs. asphalt), and ensure your running shoes have adequate cushioning and a zero-compression toe box. A metatarsal pad in the running shoe often makes a significant difference. If pain exceeds 4/10 during a run, stop and reassess. Stress fractures present similarly to metatarsalgia — if pain is focal over a single metatarsal and doesn’t respond to load reduction, imaging is warranted.

How long does metatarsalgia take to heal?

Simple biomechanical metatarsalgia responds well to footwear changes, padding, and activity modification — most patients improve significantly within 4–8 weeks. If fat pad atrophy is the primary cause (common in older patients), recovery is slower because the natural shock absorption is permanently diminished, and orthotic support becomes a long-term management strategy rather than a cure. Stress fractures require 6–8 weeks of protected weight-bearing.

Does metatarsalgia require surgery?

Rarely. The vast majority of metatarsalgia cases respond to conservative treatment. Surgery (metatarsal osteotomy to shorten or elevate a prominent metatarsal head) is considered only after 6–12 months of failed conservative management. Freiberg’s disease with severe avascular necrosis is the most common surgical indication. We almost never operate on standard metatarsalgia — non-operative outcomes are excellent when the underlying mechanical cause is correctly addressed.

What is sesamoiditis and how is it different from metatarsalgia?

Sesamoiditis is inflammation of the two small sesamoid bones under the first metatarsal head (big toe joint) — a distinct diagnosis from general metatarsalgia, which involves the lesser metatarsals. Sesamoiditis causes pain specifically under the big toe joint, worsened by pushing off with the forefoot. Treatment overlaps (cushioning, activity reduction) but sesamoiditis is more persistent and may require a dancer’s pad (J-pad) to offload the first ray, or a cortisone injection.

When should I see a podiatrist for ball-of-foot pain?

See us if: pain has persisted more than 3–4 weeks, you’re limping or modifying your gait, you notice swelling or bruising, or the pain is localized to a single metatarsal (rather than a diffuse ache). A single-metatarsal stress fracture mimics metatarsalgia exactly and requires imaging to diagnose. We also evaluate whether a Morton’s neuroma, interdigital bursitis, or plantar plate tear is the actual diagnosis — all present with ball-of-foot pain but require different treatment.
