Liquid nitrogen is extremely cold. It will freeze any living tissue it comes into contact with. Applying small amounts of liquid nitrogen to various skin problems is now a standard treatment. The medical term for this treatment is cryotherapy.

What is liquid nitrogen used for?
Liquid nitrogen treats:
Skin tags.
Small fleshy growths.
Similar small 'lumps and bumps' on the skin
These are ideal for liquid nitrogen treatment.
Is liquid nitrogen treatment painful?
العودة إلى المحتوياتApplications usually last about 10-30 seconds. Try holding a cube of ice against your skin for 10-30 seconds. It is uncomfortable but usually not too painful. Liquid nitrogen applied to skin is similar but colder and most people find the discomfort quite bearable.

What can I expect from liquid nitrogen treatment?
العودة إلى المحتوياتAfter a liquid nitrogen treatment, the lump, wart or whatever is being treated will gradually discolour and fall off.
The surrounding skin will sometimes become red and swollen and be sore for a day or so. It is similar to a mild burn.
Occasionally a blister (sometimes a 'blood blister') forms. If this happens, it is best to pop it with a clean pin and apply a plaster.
New skin quickly forms and any scab or blister will soon disappear. The appearance of the skin afterwards is usually good.
Does liquid nitrogen treatment always work?
العودة إلى المحتوياتUsually, it does. However, sometimes thicker warts or verrucas need two or more sessions of liquid nitrogen treatment over a period of a few weeks to get to the root.

Complementary and alternative medicine (CAM) is used by many people. It can have a very good effect on improving well-being and may be helpful in relieving some symptoms. However, although there is some evidence from clinical studies that CAMs may work for certain symptoms, the evidence is not very strong and it is impossible to draw firm conclusions about the benefits of each treatment. It is very important to consider whether any CAM treatment may have side-effects. Again the side-effects of some CAM treatments, particularly some herbal remedies, are not as well known as for conventional medicines. In addition, choosing to use alternative medicine instead of medically recommended treatments can sometimes be dangerous.
