Corns and calluses
Corns and calluses are areas of hard, thickened skin that develop when the skin is exposed to excessive pressure or friction. They commonly occur on the feet and can cause pain and discomfort when you walk.

Calluses are larger than corns and don't have such a well-defined edge. As callused skin is thick, it's often less sensitive to touch than the surrounding skin.
Calluses develop when the skin rubs against something, such as a bone, a shoe or the ground. Theyoften form over the ball of your footbecause this area takes most of your weight when you walk.
Activitiesthat put repeated pressure on the foot, such as running or walking barefoot, can cause calluses to form. Athletes are particularly susceptible to them.

Acorn is a symptom of an underlying problem. You should only treat it yourself if you know the cause and you've spoken to a specialist about the best way to manage it.
Over-the-counter treatments for corns, such as corn plasters, are available from pharmacists. However, they don't treat the cause of the corn and may affect the normal, thinner skin surrounding the corn.
Corn plasters may not be suitable for certain people, such as those with diabetes , circulation problems, orfragile skin.
As with corns, you should only treat calluses yourself after a podiatrist has identified the cause and advised you about treatment.
The podiatrist may be able to treat corns or badly callused areas using a sharp blade to remove the thickened area of skin. This is painless and should help reduce pain and discomfort. They can also provide advice on self-care and prescribe special insoles.
