What symptom characterizes plantar warts?

Plantar warts are characterized by excessive epidermal thickening, which occurs as a result of the human papillomavirus (HPV) infection affecting the skin on the soles of the feet. This thickening is specifically noted as a reaction to pressure, making these warts often hard and raised, and they may develop calluses around them due to weight-bearing activities.

In contrast to other symptoms that may be associated with skin conditions, such as severe itching, redness and blistering, or central umbilication, plantar warts are generally not itchy and do not present with those inflammatory symptoms. Instead, the noticeable feature is the thickened area of skin, sometimes accompanied by tiny black dots (clotted blood vessels) within the wart, which further distinguishes them from other types of skin growths. Understanding this symptomatology is crucial for accurate diagnosis and treatment in athletic training and healthcare.
