Corns - what is it?
A callus is a well-defined area of the epidermis with a core (horn plug) that penetrates deep into the skin. It is the cause of severe pain due to pressure on the nerve endings in the skin. They occur mainly in the area of the metatarsophalangeal joints, between the fingers and on their backs. It also happens that they appear under the nail plate and in the nail folds.
Types of corns:
- hard,
- soft,
- multiple,
- papillary,
- capillary,
- neurovascular,
- neurofibrous.
Causes of formation:
- mechanical irritation,
- bone deformities,

- incorrectly selected footwear,
- irritants in footwear,
- disorders in the structure of the foot: e.g. overlapping toes,
- abnormal gait biomechanics.
