Mole

ok so about three months ago I got what I thought was a wart on my leg. I bought some compound w and applied it. The only thing that did was kill the skin around the wart/mole thingy and made the skin turn black. I stopped using the compound w right away. The skin is healed now but it looks like someone took a chunk out of my leg. That was about two months ago. This thing itches like crazy and has little pieces of skin that flakes off. I know I shouldn't but I pick at it and make it bleed sometimes. Everyone says I should go have it checked out. I googled itchy flaky mole and found out those are two major signs of skin cancer. Yeah I know, never google symptoms, it's always cancer according to Google. Anyway I thought I should probably have it checked out just to be on the safe side, but my husband had to drop our insurance when the premiums got so high we couldn't afford it. I'm a stay at home wife. So now we don't have insurance and I don't know what to do or where I can go to get checked out. Would an immediate care center take care of something like this?
