Please help me. What is freezing a wart like??

I am getting my infected wart freezed off at the doctors today. He gave me an antibiotic to help the infection but Ive never had a wart. Thank you for your answers!

Cryosurgery is a method of super-freezing tissue in order to destroy it. The technique is used to treat cancerous tumors, control pain, control bleeding, and reduce brain tumors.
The cold is introduced through a probe which has liquid nitrogen circulating through it. To destroy diseased tissue, the tissue is cooled to below -20 degrees Celsius. Other procedures that control pain or bleeding are cooled to a lesser degree to prevent tissue damage.
