Hi, three weeks ago I had a wart burned off at the doctors office. I asked him to apply as much liquid nitrogen as possible and as such, the blood blister that formed afterwards was very painful. Just recently, I removed the blood blister after it had scabbed up but there is a small bump of what appears to be skin right where the wart was. Does anybody know what it may be, and if it is another wart forming, because if so I need to book another doctors appointment since it is effecting my work performance. Thank you in advance.
