Corn, Callus or Verruca: How Can You Tell the Difference?

A corn is a concentrated area of hard skin that often forms over a pressure point, such as the top of a toe, between toes or under the ball of the foot. It may feel like a small plug or pebble when you walk.

Corns are commonly linked with pressure from footwear, toe shape, joint position or repeated rubbing. Routine corn care may help reduce discomfort where the concern is suitable for a Foot Health Practitioner appointment.

Callus is a broader patch of hard skin. It often develops where the skin is trying to protect itself from repeated pressure, rubbing or shear.

Callus may appear on heels, the balls of the feet or around areas that take more load. It can return if the pressure pattern remains, so ongoing maintenance and footwear choices may matter.

A verruca is a wart on the foot. Verrucae are associated with human papillomavirus infection and can sometimes have tiny dark dots, interrupted skin lines or tenderness when squeezed from side to side.

Foot+ does not present this guide as verruca treatment. If you think an area may be a verruca, a pharmacist, podiatrist or GP can advise on suitable options.

Corns tend to be more focal and pressure-related. Callus is usually broader and linked with repeated friction or load. Verrucae may disrupt normal skin lines and can look different from ordinary hard skin.

These signs overlap. A painful area under the foot is not automatically a corn, and an area with hard skin is not automatically callus.

Lighting, skin thickness, footwear history and exact pain pattern all affect interpretation. Online photographs and descriptions cannot replace looking at the foot in context.

This is particularly important if you have diabetes, reduced sensation, circulation concerns, immune suppression, a wound or unexplained changes.

Do not use blades, scalpels, corn knives or strong acids on uncertain areas. Avoid digging into painful hard skin or cutting anything that bleeds, changes quickly or has broken skin around it.

Over-the-counter products may not be suitable for everyone. Ask a pharmacist or clinician if you are unsure.

A Foot Health Practitioner may help with routine pressure-related corns, hard skin and callus where the concern is within scope. The appointment can include conservative reduction and practical advice about footwear, moisturising and maintenance.

If the area looks outside routine foot-care scope, Adam will advise you to seek the appropriate professional support.

A podiatrist, pharmacist or GP may be more appropriate for suspected verrucae, wounds, infection, sudden severe pain, spreading redness, unexplained bleeding, or symptoms linked with diabetes or circulation concerns.

Urgent symptoms should be assessed through the appropriate NHS route rather than waiting for routine foot care.
