Hard, grainy growths that appear on the heels or balls of the feet are typically known as plantar or palmar warts. They are noncancerous skin growths, caused by a viral infection in the top layer of the skin.
Warts can be contagious and cause irritation or minor pain, depending on their location. Even if a wart is not painful, it can be unsightly, making patients self-conscious.
A wart should not be confused with a corn or callus. If you think you might be suffering from warts, make an appointment with Dr. Kruse for a diagnosis and full range of treatment options.
