I am 30 years old. I get severe headache(continious) a week before my period whish lasts for 4-5 days? Is there any remedy for the acne I get during this time? The acne takes ages to heal. As of now I am applying TRETINOIN - Retino-A .025%. What type of food do I have to take during my periods? And when will these painfull acne(nodules/ cysts) stop?
