When to See a Doctor for Corns & Calluses: Pain, Infection & High-Risk Feet

Corns (helomas) and calluses (tylomas) are hyperkeratotic responses to pressure/friction. Most are manageable at home, but certain signs mandate professional care.

Home Management (First-Line)

• Soak 10–15 min warm water → gentle pumice/file.
• Moisturize daily (urea 10–20%, salicylic acid 6–17% – avoid if diabetic/neuropathic).
• Proper footwear: wide toe box, low heel, cushioned insole.
• Offloading pads: moleskin, silicone toe sleeves, metatarsal pads.

See a Podiatrist / Physician If:

1. Diabetes, PAD, neuropathy, immunosuppression: Any lesion → professional care. Self-treatment risks ulceration, infection, amputation.
2. Signs of infection: Redness spreading, warmth, purulence, red streaks, fever.
3. Severe / limiting pain: Alters gait, prevents shoe wear, disrupts sleep.
4. Bleeding or ulceration within/under the lesion.
5. Rapid growth, color change (black/brown), irregular borders – rule out melanoma (rare but reported).
6. Failed home care: No improvement after 2–4 weeks of consistent offloading/treatment.
7. Structural deformity driving lesion: Bunion, hammertoe, prominent metatarsal head – surgical correction may be definitive.
8. Recurrent corns/calluses despite proper footwear → biomechanical assessment (orthotics, gait analysis).

In-Office Treatments

• Sharp debridement (scalpel) – painless, immediate relief.
• Prescription keratolytics (40% urea, 30% salicylic acid).
• Custom orthotics / toe props / shoe modifications.
• Injection therapy (corticosteroid for inflamed bursa/adventitial bursitis).
• Surgical correction of underlying bony prominence.

Prevention

• Shoe fit: ½" beyond longest toe; width matches forefoot; replace worn shoes.
• Moisture-wicking socks; seamless toe.
• Daily foot inspection (mandatory for diabetes).
• Regular podiatry visits for high-risk patients (every 6–12 weeks).
