One of my closest girlfriends has vulvar varicosities, and when she had her baby it was a total nightmare. I'm not even going to say the things she said to describe how she felt because they'er not appropriate for a family friendly forum.
I would like to clear one thing up that I've read about on some of the other threads about this topic (I too have the dreaded veins, and have worried about what will happen if and when I ever successfully conceive). There is a product called the V2 that was made by a company called Prenatal Cradle. I clicked the link in one of the threads (http://www.mothering.com/community/t/846057/omg-vulvar-varicosity) to the website of the company that makes them, and there was no website.
I did a little searching and found out that Prenatal Cradle, LLC is no longer in business :-(
The good news is you can still get them even though the company that makes them no longer exists. I don't know if they just changed names or what the deal is, but I was able to find the Prenatal Cradle V2, but the company that now sells is is called Egan Medical, not Prenatal Cradle.
Maybe they bought them out, changed their name or what. I don't know. But if you're actually suffering from that feeling that everything's all about to fall out you have to go here to get the supporter: http://www.eganmedical.com/Prenatal-Cradle-Plus-V2-Maternity-Support-p/ormt-pncpv2.htm
PrenatalCradle.com is a blank web page now. I tried to reply to the threads where they were touting this now defunct company, but for whatever reason couldn't comment.
