How do you get rid of plantar warts?

Professional treatments include cryotherapy (freezing), salicylic acid, laser therapy, and surgical excision. Dr. Biernacki typically uses a combination approach tailored to wart size and location. Over-the-counter treatments have limited effectiveness for plantar warts due to the thick skin on the foot sole. Most warts resolve within 2-4 treatments spaced 2-3 weeks apart. Call 810-206-1402 for treatment.

Are plantar warts contagious?

Yes, plantar warts are caused by HPV (human papillomavirus) and spread through direct contact with the virus, often in moist environments like pool decks, gym showers, and locker rooms. The virus enters through tiny cuts or breaks in the skin. Prevention includes wearing shoes in public areas and avoiding contact with visible warts.

What does a plantar wart look like?

Plantar warts appear as small, rough, grainy growths on the bottom of the foot, often with small black dots (thrombosed capillaries). They may cause pain when walking, especially with direct pressure. Unlike calluses, warts interrupt natural skin lines and are painful when squeezed from the sides. Multiple warts clustered together are called mosaic warts.

Plantar Warts Treatment & Recurrence Prevention

Plantar warts — cutaneous lesions caused by human papillomavirus (HPV, most commonly types 1, 2, 4, and 27) — are among the most common dermatological presentations in the foot and ankle. Unlike warts at other body sites, plantar warts are driven inward by body weight, producing painful intracutaneous lesions rather than exophytic growths. Management requires understanding the natural history (spontaneous resolution in 65% of immunocompetent adults within 2 years), distinguishing features from callus and corn, and selecting treatment appropriate to the patient’s age, immune status, and symptom severity.

Diagnosis and Differential Diagnosis

Clinical features distinguishing plantar wart from callus: disruption of normal dermatoglyphic skin lines at the lesion (callus follows skin lines; wart obliterates them), punctate bleeding when the lesion is pared (the prominent capillary loops in wart tissue produce pinpoint bleeding; callus does not bleed), and pain with lateral pinch pressure rather than direct pressure (warts have lateral tenderness; callus has direct plantar tenderness). Mosaic warts — clusters of individual verrucae coalescing into a large plantar plaque — are particularly resistant to treatment.

Treatment Ladder

First-line: salicylic acid preparations (17–40% concentration) applied daily after debridement with a pumice stone, continued for 12 weeks — the most evidence-supported first-line treatment. Cryotherapy with liquid nitrogen: 10–30 second freeze-thaw cycles applied at 2–3 week intervals — effective for isolated warts, less effective for mosaic lesions. Cantharidin (blister beetle extract): applied in-office, covered for 24 hours — produces a blister that mechanically destroys wart tissue. Swift microwave therapy: a newer modality using focused microwave energy to stimulate immune response to the HPV — promising early data for recalcitrant warts. Bleomycin injection: intralesional bleomycin (0.5–1mg/mL) has 70–90% cure rates for recalcitrant warts but requires multiple sessions and produces significant local discomfort. Surgical excision: reserved for truly refractory cases — carries a risk of scar formation that can be more painful than the original wart. Immunotherapy (Candida antigen or DPCP): stimulates systemic immune response against HPV — effective for multiple warts and mosaic lesions. Dr. Biernacki at Balance Foot & Ankle provides comprehensive plantar wart evaluation and treatment including cantharidin application, cryotherapy, and advanced modalities for recalcitrant cases.

When to See a Podiatrist

Many foot conditions can be managed conservatively at home, but some require professional evaluation. See a podiatrist promptly if you experience:

Pain that persists for more than 2 weeks despite rest
Swelling, redness, or warmth that isn’t improving
Numbness, tingling, or burning in the feet
A wound or sore that is not healing within 2 weeks
Any foot concern if you have diabetes or poor circulation
Nail changes that suggest fungal infection or other problems
