What are the hard growths on bottom of feet?

Plantar warts are hard, grainy growths that can appear on the bottom of the feet. They are caused by the human papillomavirus (HPV). Plantar warts are typically small, round, and have a black dot in the center. They can be painful, especially when walking or standing.

Corns are also hard growths that can appear on the feet, but they are caused by friction or pressure. Corns are usually located on the tops of the toes or on the balls of the feet. They can be painful, especially when wearing shoes.

Calluses are thick, hardened areas of skin that can appear anywhere on the body, but they are most common on the feet. Calluses are caused by repeated friction or pressure. They are not typically painful, but they can become so if they become too thick or cracked.

If you have a hard growth on the bottom of your foot, it is important to see a doctor to determine the cause and to get treatment.
