Kidney / Ovary pain

Paige
Im having a lot of discomfort over my kidney area and my left ovary area. Like a really bad throbbing pain, especially after I eat. I've had an ovarian cyst when I was like 14, but I don't really remember how it felt. I went to the ER yesterday and they told me it was a stomach bug and sent me home. I still am hurting like crazy though!
