Acid burns from mediplast wart remover?

So I had a group of five plantar warts on the side of my pinkie toe and it was so disgusting..so I bought a box of Mediplast wart removing pads and supposedly they burn away the warts. But lucky for me that wasn't the only thing it burned!! :/ I replaced the pad on my toe every day and now the warts are pretty much gone but so is 4 layers of my skin. It burns if anything even water touches it and it's very red and like raw meat. I hate it, and it makes taking the pad off even more painful. It's also beginning to spread and now half of my toe is 4 layers down on skin. What should I do?
