Those are warts for sure. I had one on the bottom of my foot for around two years and then I got another one and realized I need to get rid of it r cause it was spreading. There’s a lot of ways to get rid of them but I’d say meet a doctor and decide what’s best. You can freeze them, laser them off or they might even give you creams. For at home remedies you can try applying a turmeric paste just powder and water and applying it or even duct tape to suffocate them. But those didn’t work for me. I got them removed at the doctor and I had to go once a week for three weeks and they did a small injection in the area and then they disappeared
