Sounds like a common thrush or yeast infection at a very low level. It will not get better on its own. See your doctor and in a day or two this will go away.
I admire your looking around for a solution and I am glad there are good medical sites aorund. The key, however, is putting in complete symptoms and the risk is we "discover" we have cancer when it is really something much less threatening. The opposite can also happen.
In this case you identified the problem in your vagina when the irritation is actually on the vulva. Computers are linear and cannot identify alternatives such as this.
