I've been getting itchy red bumps on my face for about 6 months now. They are kind of hard, single red bumps. They look like bug bites almost, but I only get them on my left cheek and my forehead. If I scratch them a very little amount of clear liquid comes out, and then they scab and start to get better. They tend to get worse when I'm ovulating/menstruating, and go away almost completely when I'm not. Any ideas?
