Pain under the forefoot is not one diagnosis. Symptoms may come from an interdigital nerve, an intermetatarsal bursa, the plantar plate, a metatarsophalangeal (MTP) joint, a metatarsal bone, the sesamoid complex or mechanical overload.
Morton’s neuroma is especially important because burning, numbness or electric pain between the toes can resemble other forefoot disorders. Plantar plate injury and intermetatarsal bursitis can also produce pain in a similar region, while stress injury requires a different pathway altogether.
At our Denver Tech Center clinic, Dr. Scott King first localizes the pain source using symptom pattern, forefoot compression, toe position, plantar tenderness, nerve symptoms, loading behavior and selective imaging when necessary. Treatment is then selected according to the diagnosis and may include load modification, progressive rehabilitation, manual treatment, orthotic support where mechanically indicated, shockwave therapy for selected conditions, imaging or referral. The aim is to treat the structure that is actually producing the pain rather than the general label. Diagnosis comes first; treatment comes second.
Metatarsalgia Is a Location, Not a Diagnosis
Metatarsalgia describes where the foot hurts. It does not identify which structure is causing the pain. The term generally refers to pain in the ball of the foot around the metatarsal heads, and that pain may come from Morton’s neuroma, intermetatarsal bursitis, plantar plate injury, MTP joint synovitis or arthritis, a stress reaction or fracture, sesamoid problems, mechanical overload or a broader nerve condition such as peripheral neuropathy. Treating “metatarsalgia” without first localizing the structure is not a diagnosis-first plan.
Seek prompt evaluation for focal bone pain that builds with walking or running, swelling on top of the foot after an increase in activity, a hot, red or swollen joint, fever, numbness spreading beyond the toes or into both feet, a rapidly worsening toe deformity, or pain after a significant injury.
Morton’s Neuroma
Morton’s neuroma is a painful interdigital nerve disorder rather than a tumor. Symptoms commonly include burning, tingling or electric forefoot pain radiating into adjacent toes. It is a compressive and degenerative change in the common plantar digital nerve, most often between the third and fourth metatarsal heads and sometimes between the second and third. People often describe a pebble or a fold in the sock, numbness in the toes, and symptoms that worsen in narrow shoes and ease when the shoe comes off.
Examination looks at webspace tenderness, forefoot compression, a Mulder-type maneuver, sensory symptoms, shoe intolerance and symptom radiation. A Mulder-type click or symptom reproduction can support the diagnosis, but no single provocative maneuver should be used in isolation. A systematic review found that a patient-reported click was highly specific and a negative webspace squeeze test made neuroma unlikely, while burning pain and the pebble sensation were not reliable on their own.
Intermetatarsal Bursitis
Intermetatarsal bursitis is one of the most important mimics of Morton’s neuroma because both can produce webspace pain and forefoot compression symptoms. The bursa sits between the metatarsal heads, close to the nerve. In a prospective MRI study of 26 patients with intermetatarsal pain, 14 had bursitis and 5 had a neuroma, and ultrasound found it difficult to tell the two apart. Toes that spread apart in a V shape can point toward bursitis. The differences are explained in Morton’s neuroma vs. metatarsalgia vs. intermetatarsal bursitis.
Plantar Plate Injury
The plantar plate is a thick ligament on the underside of each lesser MTP joint that stabilizes the toe. Plantar plate injury is primarily a stabilizing-structure problem of the MTP joint rather than an interdigital nerve disorder. It typically causes pain beneath the second or third metatarsal head, swelling at the base of the toe, a toe that drifts, lifts or crosses over its neighbor, and instability on drawer testing. Abnormal MTP translation can support plantar-plate injury, particularly when the finding reproduces familiar symptoms and matches the toe-position changes. See plantar plate injury vs. metatarsalgia.
Bone, Joint and Sesamoid Causes
- Stress reaction or fracture: focal bone tenderness, load-related pain that progresses with walking or running and swelling suggest a metatarsal stress injury. This needs imaging and load protection rather than shockwave or manual therapy as a first response.
- MTP joint synovitis or arthritis: joint swelling, stiffness and pain with toe movement point to the joint itself; inflammatory arthritis is considered when several joints are involved.
- Sesamoid pathology: pain beneath the big-toe joint may come from sesamoiditis, a sesamoid stress injury or fracture, or less often osteonecrosis.
- Freiberg disease: an uncommon osteonecrosis of a metatarsal head, most often the second, usually seen in younger people and confirmed on imaging.
Mechanical Forefoot Overload
Some forefoot pain reflects a loading pattern without a neuroma or tear. The examination considers foot posture, toe function, calf capacity, intrinsic foot strength, first-ray function, footwear, training volume and how load is distributed across the metatarsal heads. Mechanical overload is not automatically a “collapsed arch”; high arches, a stiff first toe, tight calves, heel height and sudden increases in walking or running can all shift load forward.
What We Examine
- Where the pain sits: between the metatarsal heads, under a joint, on a bone or under the big toe
- Symptom quality: burning, tingling, numbness or electric pain versus aching or bruised pain
- Webspace tenderness, forefoot compression and a Mulder-type maneuver
- MTP joint swelling, drawer testing and toe position
- Focal bone tenderness and loading history
- Calf, toe and intrinsic foot function, first-ray motion and footwear
- Sensation, to screen for broader nerve problems
When Imaging Matters
Ultrasound is particularly useful when the key question is whether pain arises from an interdigital nerve, bursa or plantar plate, while MRI provides a broader structural assessment when the diagnosis remains uncertain. A meta-analysis found similar sensitivity for ultrasound (0.91) and MRI (0.90) in Morton’s neuroma. For plantar plate injury, ultrasound was more sensitive (95%) but much less specific (52%) than MRI (89% and 83%). Neither scan decides on its own whether a finding explains the pain; webspace changes are also seen in people without symptoms.
How Treatment Is Selected
Load and Footwear Modification
For appropriate mechanical presentations: footwear width, heel height, forefoot loading, activity and running volume and metatarsal pressure are adjusted according to the diagnosis rather than with universal rules.
Progressive Foot Rehabilitation
For intrinsic weakness and mechanical overload: toe and intrinsic foot strength, calf capacity and graded walking or running tolerance.
Orthotic Support
Orthotic support may be useful when forefoot loading mechanics are contributing to symptoms, particularly when redistribution of plantar pressure changes the patient’s pain. Options include a metatarsal pad, forefoot offloading, footwear modification or custom support. When custom support is mechanically indicated, Novo may use Sole Supports orthotics to modify foot loading. The goal of orthotic treatment is to redistribute load, not to claim that a device removes the neuroma.
Manual Soft-Tissue Treatment
An adjunct when surrounding mechanical restriction matters. Manual treatment may help surrounding mechanical restrictions, but it does not remove an interdigital neuroma or repair an unstable plantar plate.
Shockwave Therapy
Direct sham-controlled evidence exists for shockwave in Morton’s neuroma, with improvement in symptoms rather than neuroma size. Shockwave should be considered only after the underlying diagnosis is identified. “Metatarsalgia” by itself is not a sufficiently specific treatment indication, and shockwave is not used for an uncharacterized stress fracture or to repair an unstable plantar plate. See the shockwave evidence review and shockwave therapy in Denver.
EMTT
EMTT may be used selectively for other musculoskeletal indications, but direct evidence for Morton’s neuroma remains insufficient.
Ultrasound or MRI
Used when the structure matters for the plan: suspected plantar plate tear, stress injury, joint disease, an unclear diagnosis or persistent symptoms.
Referral
For a stress fracture, advanced plantar plate instability, progressive toe deformity, a refractory neuroma that may need injection or surgical opinion, neurologic deficit or other structural pathology requiring procedural or surgical evaluation.
You do not need to decide which treatment you need before your visit. All four tools are compared on the services page, and foot mechanics and orthotic decisions are also discussed in posterior tibial tendon pain.
What Research Says
- Metatarsalgia: a symptom category for forefoot pain, not a single condition.
- Morton’s neuroma: a compressive neuropathy of the common plantar digital nerve, and an interdigital nerve disorder rather than a tumor (Matthews, 2019).
- Mimics: intermetatarsal bursitis was more common than neuroma on MRI in a prospective cohort with intermetatarsal pain (Larsen, 2025), and plantar plate injury overlaps clinically with both.
- 2009 sham-controlled trial: in a randomized, double-blind trial of 25 patients with chronic interdigital neuroma, pain fell significantly in the active ESWT group through 12 weeks, while the sham group showed no significant change (Fridman, 2009).
- 2016 sham-controlled trial: pain and AOFAS lesser-toe scores improved after ESWT, the sham group did not change significantly, and ultrasound showed no significant change in neuroma diameter (Seok, 2016).
- Systematic reviews: a foot-and-ankle review listed Morton’s neuroma among conditions with supportive ESWT data but called for better trials (Tengku Yusof, 2022). A Morton’s-specific review found the direct comparison of ESWT against control was not statistically conclusive, with wide confidence intervals (Matthews, 2019).
- Clinical tests: a patient-reported click was highly specific for neuroma and a negative webspace squeeze test made neuroma unlikely, while burning pain and a pebble sensation were unreliable on their own (Pitcher, 2024).
- Imaging: ultrasound and MRI had similar sensitivity for Morton’s neuroma (0.91 and 0.90), while for plantar plate injury ultrasound was more sensitive but much less specific than MRI (Bignotti, 2015; Albright, 2022).
- Other neuroma evidence: a randomized trial in painful amputation-stump neuroma found greater pain reduction with ESWT than conventional care without a change in neuroma size, supporting plausibility but not proving benefit in Morton’s neuroma (Jung, 2014).
- Other conservative care: the Morton’s-specific review found the strongest pain evidence for corticosteroid injection and for manipulation and mobilization, with no gold-standard treatment identified (Matthews, 2019).
- EMTT: no direct Morton’s-neuroma efficacy data; current foot studies are small pilots and case reports in other conditions.
This is why Novo does not treat every case of forefoot pain as either a neuroma or a shockwave indication.
