Corns vs Warts: Understanding the Differences, Causes & Treatments
Corns and plantar warts are two of the most common causes of discomfort on the feet, yet they are often confused due to their similar appearance. While both can be painful and unsightly, they differ significantly in their causes, appearance, and treatment approaches. Understanding the difference is essential for receiving the right care and achieving long-term relief.
What Are Corns?
Corns are areas of thickened skin that develop due to repeated friction or pressure—usually from ill-fitting shoes, toe deformities (like hammertoes), or abnormal walking patterns. They commonly form over bony areas such as the tops or tips of toes.
Common Signs of Corns:
- Hard, rough, yellowish patches of skin
- Typically located on pressure points (tops of toes, sides of feet)
- May feel painful when pressed
- No black dots inside
What Are Plantar Warts?
Plantar warts are caused by the human papillomavirus (HPV), which enters the skin through tiny cuts or abrasions. These warts often appear on the soles of the feet and can be contracted in communal areas such as pools, gyms, or locker rooms.
Common Signs of Warts:
- Rough, grainy texture with small black dots (tiny clotted blood vessels)
- Interrupt the natural skin lines
- Can occur singly or in clusters
- Pain when walking or standing
- Spreadable to other areas or people
How to Tell the Difference
One quick test a podiatrist may use is a pinch test:
- Warts typically hurt when squeezed from the sides.
- Corns usually hurt when pressure is applied directly.
That said, the safest and most accurate way to identify them is through a professional podiatry assessment.
Causes of Corns and Warts
Corns
- Tight or high-heeled shoes
- Toe deformities (like bunions or hammertoes)
- Walking or standing for long periods
- Lack of cushioning in shoes
Warts
- HPV virus infection
- Walking barefoot in communal wet areas
- Skin trauma or cracks
- Weakened immune system
Treatment Options
For Corns:
- Footwear advice: Wearing well-fitting, cushioned shoes
- Debridement: Painless removal of thickened skin by a podiatrist
- Offloading pads or orthotics: To reduce pressure and prevent recurrence
- Addressing foot mechanics: Through gait analysis or orthotic therapy
For Warts:
- Topical treatments: Salicylic acid or other keratolytics
- Advice on hygiene: To prevent spread or reinfection
When to See a Podiatrist
If you’re unsure whether you’re dealing with a corn or a wart—or if home treatments haven’t helped—it’s best to see a podiatrist. Proper diagnosis and early intervention not only relieve pain but also prevent the condition from worsening or spreading.
Frequently Asked Questions (FAQs)
- What’s the difference between a corn and a wart?
Corns are caused by repeated friction or pressure and usually appear on bony areas of the feet. They tend to be hard and circular. Warts, on the other hand, are caused by the human papillomavirus (HPV) and can appear anywhere on the foot, often with small black dots and a rough texture. - Are corns contagious like warts?
No, corns are not contagious. Warts, however, are caused by a virus and can spread to other parts of the foot or to other people through shared surfaces like floors or showers. - Can I treat corns and warts at home?
While there are over-the-counter treatments, they are often ineffective or inappropriate for the specific condition. It’s best to see a podiatrist for proper diagnosis and safe, effective treatment—especially if you have diabetes or circulation issues. - What treatments are available for corns?
Treatment for corns may include removing the thickened skin, offloading pressure with padding or orthotics, and addressing any underlying foot mechanics to prevent recurrence. - How are plantar warts treated?
Plantar warts can be treated with topical acids, cryotherapy (freezing), needling, or other methods. The best treatment depends on the size, location, and persistence of the wart. - When should I see a podiatrist?
If you have foot pain, a suspicious lesion, or if home treatments haven’t worked, it’s time to see a podiatrist. Prompt care can prevent worsening of the condition and speed up healing.
