My left hip hurts SO bad. when I walk, it clicks. if i sit down it pops, standing after sitting has become so painful I don't even want to. and I can't lie on that side of my body? I told my OB and she said it's beyond pregnancy and I have to see my primary, then my primary dr told me it's pregnancy related but neither can do anything till after the baby is born. and sometimes when I get up too fast my left leg gives out from under me and I fall. like I'm sitting right now and I'm still in tons of pain and it radiates from the front of my hip (around my groin) all the way around to my back. could I have dislocated my hip? ??
