Hey, since gr.8 (I'm heading to gr.11 in the fall) I've been noticing bumps growing on my back, and then my chest. These bumps would always leave scars but I always disregarded them as acne or whatever. But recently things have been getting out of control, not on my back and chest, but on my upper arms. These bumps have been growing rapidly first on my upper arm but now they seem to be crawling down closer to my fore arm, (They haven't reached my fore arm yet though) the worst part is, is that they would always leave black scars in the place of the bumps. (I'm a black Canadian) These bumps are usually pretty tiny, but they do leave bigger scars. Some of which are pretty red and a couple did have a small white center. The bumps also look like a dome and look like it's erupting from the skin in a way. (I would post a picture here, but I have no clue how. ) Any help on telling me what it is, or how I can treat would be extremely helpful.
Thanks
