I am the same very painful ovulation. It starts days before I ovulate when I expect the egg/follical is growing and getting bigger and bigger. It gets to the point where its like I can feel something really big and uncomfortable in my ovary and it throbs, ache and sometimes even feels like it has its own pulse especially when I am ovulating (not the days before or after) after its finally happened it takes a few days to feel ok again like I am brusied inside. I had a laparoscopy to see and for other reasons and apparently I am fine. I asked the Gyno a few days ago and he said there was nothing he can do.

Perhaps its worth having an ultrasound to make sure there isn't a cyst there or something contributing to the pain but for me there is nothing just painful O.
