I've lately had a really dry, very sore and unbearably itchy vagina - to the point where it's been waking me up at night. I've considered it could be a yeast infection, which i have had before, but the medication doesn't seem to be doing much. There doesn't appear to be any cuts or blisters, i don't think, though i've also had small cuts, itches and discomfort a little further back around my butt.
Is there anything obvious this could be?
