You know what, when I gained a lot of weight the last time, I got on a low
carb diet and it helped me lose a lot of weight and that helped me get my period back. Maybe you should try that for a couple of months and see if it helps you too. I have heard of a few women who did the same thing and it helped them too. Cysts can cause all kinds of pain, but if you feel like you might want to try another doctor, it wouldn't hurt.
