Hi I Have Flat Warts On My Chin In A

Hi I have flat warts on my chin in a small cluster. They have been there for around 7 (or more) years. It started out as only one. but now there are a bunch huddled together on the left side of my chin. I've had them frozen once and I have tried apple cider vinegar at home once. After the vinegar treatment I thought they were gone. However, they came back. Doctors said its weird to have them for as long as I do. today I looked in the mirror and they look irritated. I don't remember bumping them or scratching them. I want them gone. What should I do??
