What is a pea-sized lump under the toe?
A pea-sized lump under the toe is most commonly a porokeratoma (deep callus core), an inclusion cyst, a fibroma, or a foreign-body granuloma from a splinter or glass shard. Less commonly it can be a Morton’s neuroma, ganglion, or soft-tissue tumor. A podiatrist can usually identify the cause clinically and remove it in-office under local anesthetic.

A pea-sized lump under a toe is most often a plantar fibroma, ganglion cyst, or interdigital neuroma. Most are benign — but a podiatrist should evaluate any growing or painful lump for accurate diagnosis.

Invalid table id.Pea-Sized Lump Under the Toe: Causes, Diagnosis & Treatment
A small, firm lump under a toe or at the ball of the foot is unsettling — but it’s almost always one of a handful of well-understood conditions. The good news is that most don’t require surgery. The key is getting the right diagnosis, because each cause has a completely different treatment approach.
The 5 Most Likely Causes of a Lump Under the Toe
1. Capsulitis (Plantar Plate Tear)
The most common cause of a pea-sized lump or “fullness” at the base of the 2nd toe. The plantar plate is a thick fibrocartilage ligament that holds the toe down against the metatarsal head. When it’s stretched or torn (from high heels, excessive toe dorsiflexion, or a long 2nd metatarsal), the joint capsule swells and the toe can eventually drift upward and cross over the big toe.
Signs pointing to capsulitis: The “lump” is actually swelling at the 2nd MTP joint; the affected toe may feel like it’s floating or lifting up; morning stiffness at the 2nd toe; pain with pushing off during walking. A positive vertical stress test (toe is pushed upward and the joint is unstable) is highly diagnostic.
2. Morton’s Neuroma
A thickening of the interdigital nerve between the 3rd and 4th metatarsal heads (less commonly between 2nd and 3rd). The “lump” may not be visibly palpable but feels like a marble or pebble under the forefoot.
Signs pointing to neuroma: Burning, electric, or shooting pain that radiates into the toes; symptoms relieved by removing the shoe and massaging the foot; Mulder’s click (a palpable click when the forefoot is squeezed) with reproduction of symptoms.
3. Metatarsalgia (Callus + Bursitis)
Chronic pressure under a prominent metatarsal head creates a thickened callus and sometimes a small fluid-filled bursa beneath it. The “lump” is the callus itself or the localized swelling. Pain is directly under the metatarsal head with standing and walking — less burning/neurological than a neuroma.
4. Ganglion Cyst
A mucous-filled cyst arising from a tendon sheath or joint capsule. Ganglions on the toes are less common than on the dorsum (top) of the foot or wrist, but they do occur. They’re usually soft, transilluminate (glow when a penlight is pressed against them), and are non-tender unless they press on an adjacent nerve.
5. Plantar Fibroma
A fibrous nodule within the plantar fascia itself — usually in the arch, not under the toes, but can present further forward. Fibromas are firm, fixed (don’t move with finger pressure), and grow slowly. They’re benign but can be painful with direct pressure.
How Podiatrists Distinguish These Conditions
In-office evaluation includes:
- Palpation and stress testing: Location, mobility, consistency, and the response to directional pressure distinguishes most causes
- Ultrasound: Real-time imaging differentiates fluid-filled structures (bursa, ganglion, cyst) from solid tissue (neuroma, fibroma, callus) and shows plantar plate integrity
- X-ray: Rules out bony pathology — prominent metatarsal head, avulsion fracture, or bony spur contributing to symptoms
- MRI: Used for plantar plate tears and when ultrasound is equivocal
Treatment by Condition
Capsulitis / Plantar Plate Tear
- Taping the toe downward (plantarflexion taping) relieves plantar plate tension — often produces immediate relief
- Stiff-soled shoes or a carbon fiber plate insert to limit MTP dorsiflexion during push-off
- Metatarsal pad proximal to the affected metatarsal head to off-load pressure
- Custom orthotics with metatarsal dome for long-term management
- Surgical plantar plate repair for complete tears that fail conservative care
Morton’s Neuroma
- Wide toe box shoes — eliminates the lateral compression that aggravates the nerve
- Metatarsal pad placed proximal to the 3rd metatarsal head spreads the bones and decompresses the nerve
- Corticosteroid injection into the interspace — effective for 50–70% of patients
- Alcohol sclerosing injections (series of 4–7) for neuromas that don’t respond to steroid
- Surgical neurectomy for cases refractory to 6+ months of conservative care
Metatarsalgia / Bursitis
- Metatarsal pad placement and cushioned insole
- Callus debridement by podiatrist (never cut calluses at home)
- Cortisone injection into the bursa if significantly inflamed
- Metatarsal osteotomy in severe cases with a prominent or elongated metatarsal
Ganglion Cyst
- Aspiration (needle drainage) with or without corticosteroid injection
- Surgical excision if it recurs or causes significant nerve compression
⚠️ When to See a Podiatrist for a Lump Under the Toe
Most lumps under the toes are benign, but a proper diagnosis is essential before starting treatment. See a podiatrist if:
- A lump or swelling under a toe persists more than 2 weeks
- You feel burning, tingling, or shooting pain into the toes
- A toe is gradually drifting upward or crossing over an adjacent toe
- You feel instability or looseness in a toe joint
- The lump is growing rapidly, is very firm, or doesn’t move with pressure
- Any lump accompanied by redness, warmth, or systemic symptoms (fever, fatigue)

Frequently Asked Questions
What causes a pea-sized lump under the toe?
Most common causes: ganglion cyst (fluid-filled, soft, common near joints), plantar fibroma (firm collagen growth, often along the plantar fascia), inclusion cyst, lipoma (fatty deposit), or rarely a tumor. A podiatrist confirms with exam + ultrasound or MRI in cases that don’t respond to conservative care.
Is a pea-sized lump under my toe dangerous?
Most are benign. Concerning signs requiring urgent evaluation: rapid growth, pain at rest, dark coloration, hard immovable mass, accompanied by numbness or fever. If the lump is soft, slow-growing, and only painful with pressure, it’s typically a ganglion or fibroma — both treatable in-office.
How do I get rid of a lump under my toe at home?
For ganglion cysts: warm compresses + cushioned shoe pads + avoid pressure. Some respond to gentle massage. For plantar fibromas: stretching + custom orthotics with a depression where the fibroma sits. Avoid the old ‘smash it with a Bible’ trick — it works for some ganglions but can damage tissue.
Should I get a lump under my toe surgically removed?
Surgery is reserved for lumps that fail conservative care, cause persistent pain, interfere with walking, or grow rapidly. Ganglion cyst aspiration takes 5 minutes in-office. Plantar fibroma surgery has a higher recurrence rate so most podiatrists try corticosteroid injections + custom orthotics first.
What does a plantar fibroma feel like?
Plantar fibromas are firm, rubbery nodules under the foot’s arch — typically pea-to-grape-sized. They’re often pain-free at rest but hurt when pressed or when walking on hard surfaces. Most patients can feel a distinct mass in the plantar fascia. Ultrasound confirms diagnosis.
Foot pain still bugging you?
A 30-minute podiatrist visit beats 3 months of guessing.
If you’ve been dealing with foot pain for more than 2 weeks without improvement, see a board-certified podiatrist. We diagnose, treat, and get most patients pain-free in under 6 weeks. Howell & Bloomfield Hills, MI.
Frequently Asked Questions
When should I see a podiatrist?
If symptoms persist past 2 weeks, affect your normal activity, or are accompanied by red-flag symptoms (warmth, redness, swelling, inability to bear weight).
What does treatment cost?
Most diagnostic visits and conservative treatments are covered by Medicare and major insurers. Out-of-pocket costs vary by your specific plan.
How quickly can I get an appointment?
Most non-urgent cases see us within 5 business days. Urgent cases (sudden pain, possible fracture) typically same or next business day.
