Corns and warts are common foot conditions that can look very similar, but understanding the difference is important as they have different causes and require different treatments. If left untreated, both can become painful and affect your ability to walk comfortably.
What is a Corn?
A corn is a thickened area of skin that develops due to repeated pressure or friction, often from tight or ill-fitting footwear. Corns typically form on weight-bearing areas such as the tops of toes or the balls of the feet.
They are caused by mechanical stress rather than infection, and are common in people who spend long periods walking, running, or standing. Treatment usually involves removing the hardened skin and reducing pressure on the affected area using proper footwear or padding.
What is a Wart?
A wart on the foot (also known as a plantar wart) is a viral skin infection caused by the human papillomavirus (HPV). Unlike corns, warts can spread and may appear in clusters.
Warts often develop after contact with contaminated surfaces such as public showers, swimming pools, or change rooms, places commonly encountered in Perth’s active lifestyle. They may also be more common in children or individuals with a weakened immune system.
Key Differences Between Corns and Warts
- Contagious: Corns are not contagious, but warts can spread through skin contact or shared surfaces
- Cause: Corns are caused by pressure and friction, while warts are caused by a viral infection (HPV)
- Appearance: Corns are hard and thickened with a central core, while warts may have a rough surface with tiny black dots
- Pain Type: Corns hurt when direct pressure is applied, while warts can be painful when squeezed from the sides
Corn and Wart Treatment in Australia
Treatment depends on the correct diagnosis. Corns are typically treated by carefully removing the thickened skin and addressing the underlying cause, such as pressure from footwear. Offloading techniques and footwear advice are key to preventing recurrence.
Warts may require targeted treatments such as salicylic acid, cryotherapy (freezing), or in some cases minor surgical removal if conservative treatments are unsuccessful.
