Hi, I m seventeen, I don t know what they are, but there s two small black bumps on the palm of my hand, I thought they were some rocks or something near the surface seeing as how I seem to fall on the sidewalk all the time. When I tried to lance them out, I just cut healthy skin, but the bumps still hurt. They re side by side, I don t know what I did, seeing as how I fall all the time and hit my hands on almost everything because I m an expressive person and use them for almost everything I do in the day. They ve been here for about two-ish days.-C
