See your doctor. There are many ways to remove a skin tag. Some people will simply clip them with fingernail clippers...Other recommend tying a piece of fishing line or dental floss around them. I recommend patients be seen for this. They can be numbed up with a tiny needle, clipped, then cauterized. Almost no pain, bleeding, or chance of infection.
Cut it off!! A physician can either excise/ cauterize under local anesthesia.
