Foot warts refer to plantar warts, and after liquid nitrogen freezing of plantar warts, you usually don’t need to sleep with a gauze wrap at night. Plantar warts are usually caused by human papillomavirus HPV infection, and they will appear as small bumps on the patient’s toes, with thickened and yellowed skin in the area of the bumps, accompanied by a painful sensation. Plantar warts can be removed using laser treatment and liquid nitrogen freezing. During liquid nitrogen cryotherapy, the low temperature generated by the liquid nitrogen is applied to the plantar warts and the low temperature encourages the necrosis of the diseased tissue in the area. As a result of the cryogenic stimulation, blisters appear on the affected area, which then dry out and crust over, and the scabs fall off to heal the warts. After the surgery, the treatment area does not need to be bandaged with gauze, but you need to pay attention to the cleanliness of the area to avoid the blisters to break the skin, so as to avoid infection. It is recommended that patients with plantar warts seek medical attention in a timely manner, and strictly follow the doctor’s instructions for treatment and protection, in order to avoid adverse consequences.
