hello. I am a female, 29, and I recently started to get a bunch of red/pink bumps isolated to my lower abdomen and sides. They spread very quickly and inconsistently itched or were extremely painful to the touch. A few of them got a whitehead, but I know they were not acneic. Over the course of about a week they stopped spreading and are now turning a brown color, almost as if they are scarring. I am now seeing a couple red bumps again and am wondering what this could be??
