Genital warts keep coming back after freezing

Genital warts are one of the most common types of sexually transmitted infections. At least half of all sexually active people will become infected with the virus that causes genital warts at some point during their lives.

If your warts aren't causing discomfort, you may not need treatment. But if your symptoms include itching, burning and pain or if visible warts are causing emotional distress, your doctor can help you clear an outbreak with medications or surgery. However, the lesions are likely to recur after treatment.

Cryotherapy
Cryotherapy (cryosurgery) destroys genital warts by freezing them with liquid nitrogen. A doctor applies liquid nitrogen to and around the warts. First, the tissue is frozen with liquid nitrogen. Then, the tissue is allowed to thaw. The tissue is frozen again, if needed. The time of application varies by the doctor who applies the liquid nitrogen and the size of the warts. The size and thickness of the warts determine the number and length of freeze/thaw cycles. Up to three treatments may be needed. You may have a mild to moderate burning sensation during the treatment. Cryotherapy is usually done in your doctor's office or clinic. A magnifying instrument may be used to see the abnormal tissue better.
Cryotherapy may be done when genital warts are visible, growing in a small area (especially near the anus), and bothersome. Cryotherapy usually is not used when genital warts are widespread.

Genital warts recurrence
Experts agree that cryotherapy can be helpful in removing genital warts. But warts may grow back. More than one treatment may be needed. In some studies, cryotherapy removed up to 90% of warts.
The removal of genital warts may not cure a human papillomavirus (HPV) infection. The virus may remain in the body in an inactive state after warts are removed.
