I have the cure! My Barnacle was on the side of my breast. My GP assured me that is was nothing to worry about and it was not cancerous. The Barnacle began to grow and the skin on it was rough. My bra was constantly rubbing and making it itch. It grew to the size of my thumb nail. I decided to treat it myself with Petty Spurge which I had used successfully in the past to remove warts. After 2 weeks it had fallen off and left only proud smooth skin. There is scar tissue which is slowly healing with the help of Arnica Cream.
If you decide to try Petty Spurge – Be warned, it is extremely powerful!!!!!
One tiny drop twice a day only on the Barnacle itself. Avoid any contact with surrounding skin! I couldn't be happier to be without my Barnacle.
