Oh well, I went by the photograph, indeed if you have torn a wart yes,you are right!
I don't think it's that because it's way smaller. It only looks like a crater because i peeled some of the skin off to see what was under, and it was this crater with the red stuff in the center but very small. I'm not sure if it's a wart though; it's directly on the crease where the uppermost joint is in my ring finger
More a pyogenic granuloma than a wart.
