Contractions WAY more intense after breaking of water?

Amanda
After reading other mothers birth stories, it seems like a common theme that contractions got way more intense and painful during an induction of labor after they broke your bag of water.  I know that was the case for me!  My contractions were 1 or 2 with pitocin and about 10 minutes after they broke my water, they were an 8 or 9 out of 10 on a pain scale.  I went from 4cm prior to complete and pushing within 2 hours.  
My goal was to go medication free but ended up getting an epidural.  I question whether I would have been more prepared and able to cope if they would have warned me that this could happen.  It got intense so quickly and contractions were coming every 2 minutes that it took me by surprise and I didn't handle it well.
