What should you know about human papillomavirus infection freezing?

A clinician applies a very cold substance to a wart for a controlled period. The treated tissue is damaged and then sheds as the skin heals. Cryotherapy is generally used for external genital or nearby anal warts that can be seen and reached; it is not a treatment that clears every HPV type or treats an HPV-positive test by itself.

The area may sting, burn, swell, blister, or feel tender for a short time. A small scab or change in skin colour can occur while it heals. Warts can return because HPV may remain in nearby skin, and a clinician may recommend another treatment session or a different approach.

Before treatment, tell the clinician if you are pregnant, have reduced immunity, take medicines that affect bleeding, or have had a reaction to a previous skin treatment. Do not apply household wart removers to genital skin.

Afterward, keep the area clean and follow the wound-care instructions you receive. Avoid rubbing or picking the treated skin. Ask when sexual contact, swimming, or exercise is suitable, because the answer depends on the site and how the skin is healing. Condoms or other barriers can reduce, but do not eliminate, the chance of passing HPV through uncovered skin. Keep recommended cervical screening appointments; a Pap Smear checks cervical cells and is separate from wart treatment.

Contact the treating clinic if pain, swelling, redness, discharge, or bleeding is worsening rather than settling, or if you develop fever or trouble passing urine. Seek urgent help for heavy bleeding, rapidly spreading swelling, or difficulty breathing after a treatment.

Arrange an assessment if a growth is bleeding without being touched, looks unusually pigmented or firm, or does not behave like the wart your clinician diagnosed. A new genital growth needs an examination because not every bump is a wart.

Ask which lesions are being treated, whether a biopsy or another examination is needed, how many visits may be considered, and what symptoms should prompt a call. You can also ask whether you need cervical screening, whether a partner should be assessed, and when HPV vaccination is appropriate for you.
