Have you had your thyroid checked? Thyroid is almost always one of the first things my doctor checks when I have problems like these. Its just a blood test. I recently went to my doctor too, because my PMS was getting SOOOO bad, and my energy levels were in the negatives. She put me on Aviane, low dose bc similar to Yaz. PMS symptoms have lightened up but I too have that horrid acne. When I read that I was like OMG ME TOO!!! Its terrible, around my jawline and chin area, and sometimes right around the nostril. They hurt something aweful. It doesn't seem to be getting any better. I've always had acne in that area around my period. I'm really wishing I could try that stuff that the celebrities promote...grrrr what it is.....you know that stuff that Jessica Simpson does commercials for? Why can't I think of the name....anyway have you tried that?
