Found a verruca last week on DCs foot. Scrubbed it daily (with hard skin remover thing), and again today. They were giggling away so not painful. Did 20 scrubs tonight, all laughing. When I pulled scrubber away, there was blood coming out of a small hole in their foot. Still laughing though as it tickled! Once it stopped bleeding, there was an obvious small hole. I put some antiseptic on and a plaster. Have I removed the verruca? Is it gone? I have no idea.
