What do I do now?

So my insurance doesn't cover freezing. I tired the whole medicated bandaid but it burned. So... I decided to just put a bandaid on and sand it. It damaged my skin from the bandaid but today looks like it's mostly gone. I say mostly because upon close inspection I still see some. Is it gone or will it come back? First picture before sanding. Second after sanding Third picture today. Fourth picture what happened to my poor finger from the waterproof bandaid 5-7th is close up. Lol I still see blood vessels and see the outline. But could that be scar? Or is this one I need freezing? Because I'm trying to get that help. I have multiple warts on my hands and this one was the biggest issue. Every time I used my hands it hurt. Every time I washed dishes it hurt and throbbed.
