What Causes Pain In Ovaries, Weight Gain And Loss Of Eyebrow Hair?

Hello I have several questions if thats ok. I will ask them all at once so you can take your time to answer. I have terrible pain in my left ovary. I went to 3 different hospitals and all they said was I have a small cyst and im fine. The pain has moved to both sides along with nausea. I have also been on painkillers because of the pain that have been prescribed by the doctors. I havent gotten a straight answer what else could this be? Also I am gaining weight and my eyebrows are slowly falling out. Im nervous and without health insurance. Should I be worried? Thank you so much for any info
