You may want to try treatment by way of compression therapy. There's a Michigan-based company that makes a product called a V2 Supporter that is used to treat vulvar varicosities. Maybe it would help bring relief to those suffering from vulvodynia.

I can't promise it will work, but I also don't know that it's ever been tried. Here's the URL: http://www.eganmedical.com/V2-Supporter-p/ormt-v2s.htm
