My Daughter Is 23 And Has Started Having Significant Acne

My daughter is 23 and has started having significant acne on her face (she has always had a perfect complexion) she is also suffering from daily headaches (some are migraines). She has complained of back and abdominal pain off and on over the past month. She has a history of depression and anxiety and an eating disorder (anorexia) which is now under control (she is at a healthy weight). She has always had heavy periods but is on birth control which has helped. I am wondering if she might have polycystic Ovarian Syndrome?
