Tests and diagnosis

By Mayo Clinic Staff

Tests and procedures used to diagnose corns and calluses include:

  • A physical exam. Your doctor will examine your feet and rule out other causes of thickened skin, such as warts and cysts.
  • An X-ray. Your doctor may recommend an X-ray of your hand or foot to see if a physical abnormality is causing the corn or callus.
