The limits of science

It's sometimes worrying how little scientists know about specifics. At present I'm in quite a lot of pain because (I assume) of ovulation. Apparently one in five women experience this, but for me it's not a regular thing: sometimes it's painful, other times there's nothing, and the pain varies from a mild sensation to full-on curled-up-on-a-sofa agony (actually, it feels a little like trapped wind). Anyway, there's a few theories, but doctors genuinely don't know what specifically causes the discomfort. I find this to be incredibly annoying!
