Corns are mostly caused by the prolonged and repeated friction and compression of a foreign object that has entered the skin, resulting in a hyperproliferative lesion. They are generally small and can be completely treated with common corn ointments. However, if a corn has been present for a long time and has grown larger, it is recommended to seek treatment at a formal hospital's dermatology department using the method of liquid nitrogen freezing, which usually resolves the issue in one or two sessions. Some corns can become larger and may be painful or show signs of inflammation and infection. In such cases, it is advisable to visit a surgical or dermatology department for a minor minimally invasive surgery to completely remove it. When wearing shoes, it is essential to choose loose and soft-soled footwear, and avoid walking barefoot on surfaces to prevent foreign objects from entering and causing the recurrence of corns.
