I'm glad you're experiencing some relief. I've had this in the past (only with my girls really) and it is horrific. My doctors also said "it's normal" and to "wait it out" or "here, take a vicodin." It is NOT normal, waiting it out is pointless, and vicodin is like popping jolly ranchers for this type of pain.
The only thing that ever helped me was using a maternity belt. Without it, I couldn't walk. I had to do a funky sideways shuffle to get from where I slept (the living room recliner!) to the bathroom and back. I should have tried a chiro, but I wasn't as naturally minded back then as I am now.
