PCOS but maybe something else too?

Phil

Hey! So when I was about 17 my periods started getting a lot more painful which was unusual for me. I had a major loss of appetite and the pain would be so bad I’d be close to fainting. When a doctor finally stopped to listen to me, I had a scan done and found that I have PCOS. it explains the acne, and sudden weight gain but many sources tell me pain isn’t an indication. I was put on birth control and the pain initially reduced a little bit but now it’s back. Please help
