There are different ways to remove a skin tag. Most tags are easily removed in a doctor's office with or without a local anaesthetic.
Depending on the size and the position of the tag on the body, the doctor will decide if a local anaesthetic is necessary or not.
If you need a local anaesthetic. An injection of lignocaine will be given to the nerve in the area where the tag is located.
The needle used for this is very small in size and you will hardly feel it.
After several minutes the area is dormant and the doctor will proceed removing the tag with sharp scissors, or cut and burn with a cautery machine.
If you don't need a local anaesthetic, then usually a freezing agent is used. The doctor freezes the tag, and then tears it off.
There are also freezing agents available to do it yourself. Other methods of do it yourself is to tie the base of the tag with dental floss, or you could also use a piece of cotton.
After a few days the tag will fall off.
Another do it yourself, which is a highly recommendable method is to use the following oils to remove the tags.
For more complex tags, these are the ones with deep roots, surgical removal is usually performed.
This is usually the case with anus tags caused by hemorrhoids.
