Callous is a yellowish plaque of hard skin and a corn is a localised cone of the same hard skin which is pushed into the skin causing pain. Both are associated with intermittent pressure, or friction. Corns may also occur between the toes. If not treated the underlying tissues may breakdown leading to ulceration or infection.

Symptoms may include:

  • hard thick area of skin
  • feeling as if there is a stone in your shoe
  • pain in the area of the corn
  • inflammation surrounding the corn
