I've been getting red bumps on my abdomen that look like acne, but it isn't. My dermatoligist didn't know what it was and wanted to perform a biopsy, but my parents refused. They are widespread and only on my stomach and sides, and last for about day, then go away and more come. They are red with a white head. When squeezed, it's like popping a zit. I also used to get these on my thighs, but that went away. Also, I get these on my breasts. They are all over and sometimes get so bad I look like a burn victim. Any ideas what it could be?
