Finding a painful lump on your foot can be confusing. Is it a harmless corn or a contagious wart?
While corns are layers of thickened skin caused by friction, warts are viral infections that can spread to other parts of your body.
Since the cause is entirely different, the methods for removing them are distinct as well. As such, it’s important to have a professional look at your foot lump to properly identify whether you have a corn or a wart.
Wart vs Corn: The Fundamental Difference
Warts and corns are not the same, as they have entirely different causes.
The Corn: A Protective Buildup
A corn is essentially a buildup of dead, thickened skin (hyperkeratosis) caused by sustained external forces, such as pressure and friction, on the foot. It’s also the body’s protective response to prevent blisters or irritation underneath. And importantly, corns are not contagious like warts.
Usually, we see two types of foot corns. Hard ones, such as seed corns, form where pressure is concentrated over a small bony area. Soft corns, on the other hand, occur where skin is moist, usually between the toes. And while they resemble hard corns, they are softened by continuous moisture.
The Wart: A Viral Infection
In contrast to corns, plantar warts are viral infections caused by the human papillomavirus (HPV). Because the cause is viral, warts are contagious and can spread to other parts of the body or to other people.
Also, warts on the sole of the foot grow inwards due to body weight. Consequently, you might feel pain while walking when you have a plantar wart.
How Do I Know if I Have a Wart or Corn on My Toe or Foot?
To identify whether you have a wart or corn on your foot, you need to review the kind of pain you’re feeling, the appearance of the lump, and its location:
- Pain: A corn causes sharp, immediate pain when pressure is applied directly downward (like stepping on a small pebble). Meanwhile, a wart causes pain that is often tender and diffuse, and significantly worse when the lump is squeezed from the sides.
- Appearance: Corns look translucent, waxy, and have a uniform colour, usually found over bony areas. Warts often appear “cauliflower-like” and may have tiny, dark specks (clotted blood vessels) inside.
- Location: While both appear on the sole, warts typically interrupt the natural lines/ridges of the skin, whereas corns do not. Additionally, corns are almost exclusive to the feet, but warts can appear anywhere on the body.
Professional Management: Why Self-Treatment Isn’t Recommended
Attempting DIY foot corn removal often fails because it ignores the root cause: underlying pressure or biomechanical imbalance. Podiatrists provide safe removal using sterile drills and address these factors, offering a long-term solution essential for preventing recurrence, especially in individuals with diabetes or circulatory issues.
In contrast, warts require controlling the viral infection, not just removing the surface skin. Dr Foot Podiatry offers targeted foot wart removal methods, including options like:
- Microwave therapy, which stimulates a targeted immune response.
- Chemical applications like cryotherapy or salicylic acid.
