TREATMENT OF SKIN CONDITIONS BY FREEZING
Freezing treatment is a carefully controlled cold burn. After the procedure, you may notice some soreness or pain; this will depend on the length of the freeze and the area being treated.
After treatment, marked redness always occurs, together with some swelling; the degree of swelling depends on the site of the treatment and its duration, but these changes usually only last for a few days.
In some people, particularly where the skin is rather thin and sensitive, a water (or blood) blister may form and fluid may discharge. If a blister does form, simply let out the fluid with a sterile pointed instrument and repeat this until the blister no longer refills.
If you are 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 may use any antiseptic cream twice daily, to avoid the small chance of infection.
Once the fluid discharge/blistering stage is over (usually a few days, unless the condition of your skin necessitates prolonged freezing) a crust or scale may form.
If undue discomfort or pain occurs after the treatment, then take Paracetamol.
Freezing treatment may result in localised pigmentary change or leave a scar.
