Common problems

Corn and callosities

Corn consists of a localised thickening of the skin cornea, which forms a core in the shape of a cone, and is often painful. They can be found on the articulations of hammertoes (hard corn), between the toes (soft corn), or on the foot sole.


Callosities are a diffuse thickening of the skin of variable sizes, typically observed under the foot’s forepart or the heel.


Both these foot issues are often caused by shoes that are not adjusted adequately; they can also be the result of a mechanical instability of the foot that creates a friction or a repeated overload of pressure on the affected area. Dry skin is also a common initial factor.

The podiatrist is the professional who has the knowledge to treat corn and callosities in a safe and sterile fashion, using scissors, a burr, or a scalpel. Podiatrists may also use and prescribe unguents and lotions. They may also make some suggestions related to the selection of proper shoes.

If necessary, the podiatrist assesses the mechanical function of the foot and inferior limbs to identify the origin of the problem.

It’s not recommended for people to try to remove corn and callosities on their own using scissors or razor blades. The use of limestone should be limited to once or twice a week, solely on the heel, because using it on the forepart or the toes may cause the skin to become irritated.

Using commercial chemical products to alleviate corn and callosities is not recommended for people with diabetes and people suffering from peripheral vascular diseases. Using moisturizing lotion and applying a pad may bring some relief.

Feel free to request a consultation.
