ongoing menstrual-like cramps, anyone else suffering?

I told my doctor about them and not worried, just miserable. Anybody else?
 For the past week or two I've had them on and off, this week it's progressed to extremely painful and lasting hours at a time. I've now had them for over 24 hours, ranging from pretty painful to verge-of-tears painful. Just need people to commiserate with.
