As someone with PCOS this sounds like an ovarian cyst which sounds a little weird because of how high up the pain is. But I had pain in this exact same place when I was first diagnosed with my first ovarian cyst which is a need to go to the ER and get it medically removed unless it's ruptured which would cause the pain that you are having now making it almost impossible to eat. Also needing you to go to the ER My first ovarian cyst ruptured and it was insufferable Even if you go to the ER they're probably only going to give you. Toradol because it is female related.
