Can infections be diagnosed without examination?

[effydesmarais.livejournal.com]

I'm pretty sure I have some kind of infection. Maybe a yeast infection, but I'm pretty sure it's something else. Anyway, I'd like to get it checked out, but because of my vulvodynia and vaginismus, examinations are horrific for me, and I avoid them like the plague. I really can't stand the thought of being examined.

So is there a way for them to do it without examining me, or examining me in a really gentle/non-invasive way?

I'm in the UK by the way, just in case examination procedures differ from country to country.

Also, is there any way you can clear up an infection - yeast or otherwise - by yourself at home with natural products? Or is that just too much to hope for?
