Cryosurgery is the treatment of lesions with the application of a cold substance. In most cases, liquid nitrogen is used to destroy the lesion(s). After the treatment with liquid nitrogen, there may be a burning sensation or pain that can last up to 24 hours. This discomfort can be relieved with Extra Strength Tylenol or similar pain relief medication.
Within 24-48 hours a blister may form (i.e. clear blister or red blood filled blister). If a blister appears DO NOT drain or open the blister! Other reactions that may occur include but are not limited to: swelling around the treated area, the formation of a black scab, discoloration of the surrounding skin, persistent redness or a white or dark spot at the related site.
