Cryotherapy is a standard treatment for warts and can be done in a doctor's office. The liquid nitrogen application usually takes less than a minute.

• Your doctor may trim the wart with a small knife before applying liquid nitrogen.
• Cryotherapy can be uncomfortable.

  A numbing local anesthetic is usually not needed but may be used in some cases.

• Your doctor applies the liquid nitrogen to the wart using a probe or a cotton swab. Liquid nitrogen can also be sprayed directly on the wart.

Most warts require 1 to 4 treatments, with 1 to 3 weeks between each treatment.

There are over-the-counter products to freeze warts.

What not to do after freezing a wart

These products are less powerful than liquid nitrogen. They may work for some warts, but it may work better to have your doctor freeze the warts.

What To Expect

Pain from cryotherapy can last up to 3 days.

Healing is generally quick (7 to 14 days) with little or no scarring.
