Cryotherapy for Warts
Cryotherapy involves freezing a wart using a very cold substance (usually liquid nitrogen). 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.
Most warts require 1 to 4 treatments, with 1 to 3 weeks between each treatment.
What To Expect After Surgery
Pain from cryotherapy can last up to 3 days. Healing is generally quick (7 to 14 days) with little or no scarring.
Within hours after treatment, a blister may form.
Multiple treatments may be needed to get rid of the wart.
Why It Is Done
Cryotherapy is usually used if salicylic acid treatment has not eliminated a wart or if quick treatment is desired.
How Well It Works
If done carefully, cryotherapy poses little risk of scarring.
If a wart is thick and requires extensive or repeated freezing, nerves around the wart can be damaged, scarring may occur, and the skin may take a long time to recover.
There is a small chance of infection associated with cryotherapy. Some signs of infection include:
What To Think About
If you can tolerate moderate, short-term pain, cryotherapy may be a reasonable treatment option for you.
