What is Corns?

A corn is your skin's shield turned problem: a small, hard, thickened patch that forms exactly where a toe or the ball of the foot takes repeated pressure and friction. It is the body protecting deeper tissue - but the shield itself starts to hurt.

What it actually is

Skin thickens wherever it is repeatedly pressed and rubbed - a completely normal defense. When the pressure concentrates on one small spot (a toe joint pushing against a tight shoe), the thickening forms a dense central core pointing inward, like a pebble pressing into the foot with every step. That core is why a corn hurts sharply when pressed, unlike a flat callus.

Corn, callus or wart - the classic confusion

• Corn: small, raised, with a hard central core; hurts when pressed directly; sits over bony pressure points
• Callus: a larger, flatter thickening without a core, usually on the sole or heel; rarely painful
• Wart (verruca): a viral growth - interrupts the skin's fingerprint lines, may show tiny black dots, and hurts more when pinched sideways than pressed. Warts spread; corns never do

Where corns appear

Tops and sides of toes (especially the little toe and hammer toes), between toes (soft corns), and the ball of the foot. Each location tells the story of its pressure source - usually the shoe meeting the bone.

The reassuring headline

Corns are benign, extremely common, and never turn into anything dangerous. But they are a message: something about your footwear or foot shape is loading one spot too much. Remove that pressure - better shoes, padding, occasionally a foot specialist's help - and most corns soften and fade. The articles in this section walk through causes, types, safe home care, products, prevention and special situations.

One-line summary

A corn is a small, core-bearing patch of thickened skin built by pressure and friction - benign and curable by removing the pressure that created it, most often the shoe.
