Treatment by Liquid Nitrogen What is it? The freezing treatment you have received today is a carefully controlled cold burn with liquid nitrogen to a temperature well below zero. What to expect The reaction depends upon the amount of freezing, the site and your own reaction to the freezing. Pain – Stinging or burning starts during treatment and may continue through thawing, but settles down with a few minutes. Redness, swelling or blistering – This can be expected and in a day or two a water (or blood) blister may form, especially where the skin is thin the sensitive. Crusting – The frozen area will form a crust, which may peel or drop off in a week or two. A further scaly crust may form on the wound. It will then heal. Colour Change – When the new skin grows in the treated area it may appear paler or darker than the surrounding skin. Scarring – This is very uncommon with light freezes, but does occur with the longer freezes needed to treat larger or deeper lesions. What to do If you develop mild pain later take a paracetamol in normal doses. If it is severe consult your doctor. It is advisable to keep your healing burn as dry as possible. If you have been prescribed a cream to use, apply it twice daily. Areas which are weeping can be covered with a clean dry dressing. If you have not received a prescription you can apply an antiseptic cream twice daily to avoid the small chance of infection occurring. After the procedure The treated area can take 10-14 days to completely heal. If you become concerned about the wound contact your doctor’s surgery.
