What is a corn on the foot and what causes it to develop?

A corn on the foot is a thickened area of skin that forms as a response to pressure or friction. This often occurs on the toes or the soles of the feet, usually caused by ill-fitting shoes or repetitive activities that irritate the skin. The body creates this thickened skin as a protective measure against ongoing irritation.

Key points:

  • Corns develop due to repeated pressure or friction on the skin.
  • Poorly fitting footwear is a common cause.
  • Certain activities can contribute to their formation.
  • Skin irritation can be exacerbated by physical factors.
