The reason I ask, is because not only do I k now TONS of pregnant women it's happened to (to the point that they don't want to get pregnant again), but I've also had it happen to me, more than once. With my last, the chiropractor did NOT help, but when I looked at DH's charts (he was still in school, and I hadn't gone yet) and managed to isolate "what hurt", and I was able to "fix" the problem myself within a matter of days. There has GOT to be a way to either treat this, or teach ladies how to help themselves. With bones/joints, come muscles. I understand that often it is due to a misalignment in the pelvis, which would require a chiropractor's help. But that last time for me, it was a literal pulled muscle- I know it was from my position during birth, and the strain, of birthing a posterior-presented baby. The chiropractor only hurt me trying to "fix" it.
