I have been through the same thing with my last 3 pregnancies and didn't know there was a name for it until now! (I'm 24 weeks pregnant atm with my 4th and didn't experience it with my first) I am so happy to hear that I'm not the only one going through this like I thought I was! Personally, it's worse after I have sex , even though it gets painful if I stand for long periods, and the swelling type feeling is always there no matter what I do! =( If I have to describe it, it's like my 'lips' are going to explode! (Sorry for the TMI lol) But thanks for the question, it's helped me a lot! And yes, I do have to agree that it goes away after birth!
