Concern

Corns Treatment in Canary Wharf, London

A corn (heloma) is a small, deep area of hardened skin with a central core that forms where pressure or friction is concentrated, most often on the toes, and our HCPC-registered podiatrists can safely reduce it and treat the cause.

Corns

The concern

A corn, known clinically as a heloma, is focal nucleated hyperkeratosis: the skin thickens and forms a dense central plug in response to repeated, concentrated pressure or friction, usually over a bony prominence on a toe. Hard corns appear on the tops or tips of toes; soft corns develop between the toes, kept moist and macerated by sweat. They differ from calluses, which are broader and have no core, and from verrucae, which are viral and often show tiny black dots. The NHS advises that a podiatrist can safely remove corns and treat the underlying cause, and that you should never cut them yourself or use medicated corn plasters if you have diabetes or poor circulation. At our Canary Wharf and City Dock (Wapping) clinics, we debride the corn, relieve the pressure source, and advise on footwear and biomechanics to reduce recurrence. You can self-refer and book online; no GP referral is needed.

What drives it

  • Concentrated pressure or friction over a bony prominence, most often a toe joint or the tip of a toe
  • Footwear that is too tight, too narrow, or has a raised heel that forces the toes against the shoe
  • Toe deformities such as hammer toes, claw toes, or prominent joints that rub inside shoes
  • Soft corns between the toes, where trapped moisture and a tight toe box macerate the skin
  • Altered foot mechanics or gait that loads one area of the foot more than it can tolerate
  • High activity levels, prolonged standing, or being on hard surfaces for long periods

Common
questions

Can I use corn plasters from the chemist to remove a corn?

We do not recommend over-the-counter corn plasters. Most contain salicylic acid, which cannot tell healthy skin from the corn and can burn or ulcerate the surrounding tissue. They are specifically dangerous if you have diabetes, peripheral arterial disease, or reduced sensation. A podiatrist removes corns safely and treats the cause.

What is the difference between a corn, a callus, and a verruca?

A corn is small and deep with a hard central core, forming over a pressure point on a toe. A callus is a broader, more diffuse area of thickened skin with no core. A verruca is caused by a virus, can appear anywhere on the foot, and often shows tiny black dots. A podiatrist can tell them apart on examination.

Will a corn come back after a podiatrist removes it?

Removing the corn relieves the pain straight away, but a corn forms because of pressure, so it can return if that pressure continues. Lasting results come from changing the cause — better-fitting footwear, padding or offloading, and, where needed, a biomechanical assessment. Many people need occasional maintenance appointments rather than a one-off cure.

When should I see a podiatrist urgently about a corn?

Seek same-day or urgent medical care if a corn or the skin around it becomes red, swollen, hot, or starts leaking pus or fluid, or if you develop a fever — these can signal infection. If you have diabetes, poor circulation, or numbness in your feet, do not self-treat at all; book a podiatry assessment promptly.
