\ud83d\udc40 What is a corn?<\/h2>\n\n\n\n

A corn is a skin condition that forms on the feet or hands, typically about 5 mm in diameter.<\/mark><\/p>\n\n\n\n

It most commonly develops on the feet of adults and, once it appears, tends to cause significant pain when walking.<\/span><\/p>\n\n\n\n

Corns are caused by repeated friction or pressure on a specific area during walking or similar activity, which leads to a thickening of the outer layer of skin.<\/mark><\/p>\n\n\n\n

Because children\u2019s skin is softer, corns are less likely to develop in younger individuals. If similar symptoms appear in a child, there is a good chance they may be viral warts rather than corns.<\/mark><\/p>\n\n\n\n

\ud83e\udd14 Why do corns develop on the feet? Causes explained<\/h2>\n\n\n\n

Corns are caused by external stimulation.<\/mark> Continuous friction or pressure on the skin causes the outer layer to thicken and harden.<\/mark><\/p>\n\n\n\n

For example, \ud83d\udc60 wearing shoes that do not fit properly or wearing high heels for extended periods,<\/mark> or walking in a way that places excessive load on one part of the foot, can make corns more likely to develop.<\/p>\n\n\n\n

With corns, the skin does not simply harden on the surface \u2014 a firm central core forms deep within the skin, pressing on the underlying nerves.<\/span><\/p>\n\n\n\n

As a result, many people experience significant pain even during normal walking.<\/mark><\/p>\n\n\n\n

\ud83d\udc8a How are corns removed and treated? Treatment options<\/h2>\n\n\n\n

There are two main approaches<\/mark> to treating corns.<\/p>\n\n\n\n
