Warts and corns are thickened, rough pieces of skin that commonly develop on the hands, feet, and other body parts. Warts are typically caused by viruses in the human papilloma virus (HPV) family, and corns are caused by pressure or friction – usually on your feet due to shoes that don’t fit properly.

Warts and corns are mostly harmless, although the virus that causes warts is contagious and can be spread to others through direct contact. Warts can be itchy, especially on the feet, and both warts and corns can be uncomfortable if you put pressure on them as you walk.
