I have no idea what this is called. I'm 21 weeks (3rd baby) & if I lay (especially on my side) for too long, when I go to get up, it feels like my hips are going to break or come out of socket. They are so stiff & painful! What is this? It's right in my crotch region, like the bikini line on both sides.. Is it lightning crotch? I don't think it's sciatica since that pain goes down your leg right? I vaguely remember this with my other 2 pregnancies, but not this early or this bad.
