It sounds like candida to me. You might try baking soda swabs, or apple cider vinegar swabs (don't combine those two things - they cancel each other). If you're sore on that spot, those things may burn, so be careful.
If either of those swabs help you, it's a good bet that it's candida. The swabs should provide immediate relief and still you'll have to do them everday, because your problem isn't generated from that place, I'll bet.
I hope you find the right answer to your troubles & that you feel better. Carrie
