WHAT IS WRONG WITH MY VAGINA?

Have been experiencing discomfort, and noticed that the vulva was inflamed. This inflammation continued to get worse within the past day, and I have noticed that the vaginal tissue near the entrance of the vagina is a bit swollen, very inflamed, and speckled in white. I thought this may be a yeast infection, but have not experienced any discharge, and no fowl odors are present. Symptoms have been present for 2 days; did not have sex for at least 3 days prior to onset of irritation. SUGGESTIONS? PLEASE?
