So me and my girlfriend have been getting red bumps all over our body for the past couple of weeks. They start out looking small, like a pimple . Then a day or two later, they are about the size of a pencil eraser, an almost bumpy circular edge, and the center looks like dry skin or like a scab. They are mostly on the arms, some on stomach/back, and now I have a few on my legs. They are slightly in clusters, but not all of them. We thought bed bugs or mites, but haven t seen too much evidence of either of those. It s getting worse, and we don t know what to do. Btw, if needed to know, we are both 21 year old females.
