What should you know about dry ice for warts?

Dry ice can cause a cold burn, blistering, tissue injury, and prolonged healing when it touches skin. It does not selectively identify wart tissue, so nearby healthy skin may be damaged too. A wart can also be mistaken for a corn, callus, mole, or another lesion; treating the wrong growth may delay diagnosis. Medical Cryotherapy (Lesion Removal) uses controlled application by a trained professional, with the method chosen for the lesion and its location.

Do not hold dry ice against the growth, wrap it onto the skin, or attempt to freeze a blister that has already formed. If contact has occurred, move away from the material, do not peel stuck skin, and seek medical advice for blistering, numbness, severe pain, colour change, or a wound. A clinician may discuss Wart Removal, Electrosurgery, or selected prescription options such as Imiquimod Treatment, depending on the diagnosis.

Seek prompt assessment after any suspected dry-ice burn, particularly on the face, hands, feet, genitals, or over a joint. Arrange review if the lesion bleeds, changes quickly, becomes painful, or returns after treatment. People with diabetes, reduced sensation, poor circulation, or immune problems should obtain advice before attempting any lesion treatment.

Is this definitely a wart? Which removal method fits its size and location? What wound care should I use afterward? Could a prescription treatment work, and what symptoms after treatment need urgent review?
