I have an embossed skin in my face, beside the nose, it's like a hill, like 1cm or less in diameter, it was not like a pimple, since it is not that red, it's like a mosquito bite, but it's not (cause I get this like thrice a year, and now my my curiousity cannot be contained anymore.)
I wonder of what kind of pimple is this, it's causes, and how to heal it.
