I havent heard of that before but interesting you posted about it as I am seeing my gyno next week as have been having ovarian pain for months - which weirds me out as I am on the pill so not ovulating. I have PCOS so when I do ovulate - when not on the pill (which isn't often) I have intense, awful pain and it feels similar to this. Will be interesting to see what my specialist says. My GP wondered if my endo has spread to my ovaries causing pain.
