Cysts in or around the ovaries may be a sign of a number of things, including but not limited to PCOS. I also have cysts around my ovaries and was diagnosed with multicystic ovarian syndrome. My OBGYN is one of the top docs in Chicago and has practiced for 30+ years. So, basically, he's seen it all.
Please note, multicystic ovarian syndrome is different than polycystic ovarian syndrome. My doctor has seen fit to start treating me with Yaz, a diffeent type of bith control than I was already on. He said that I should stay on it until I'm ready to get pregnant, then get off it for a few months then try to conceive.
Anyway, that's how I'm being treated. You should check with your doctor about the night shift issue (and double check about any treatment suggested in these forums including here).
Cysts in the ovaries are sign of PCOS. There is no known cure for PCOS. I have PCOS too. Doctor will put you on BCP to regularize your periods if you are not ttc. Usually they put you on metformin that takes of the cysts to some extent. What treatment are you going through?
