Does anybody have redness but no skin condition?

I've had numerous tests and examinations over the years and have very much been told it's mental... Argh! But what really frustrates me is that even though everybody has said my vulva/vagina look healthy and perfect, to me it feels absolutely raw and looks really red? It's especially frustrating because I can pinpoint which parts of my flesh with a mirror are the most painful, but I just get told they look normal!

Anyone had this too? Or is this unusual with vestibulidynia?
