It certainly doesn't sound like a yeast or fungus, since the kind of treatment you used wouldn't have made those go away, even for a short while. I'm not certain from what you write that you have anything wrong with you. Maybe you just have some redness left over from the irritation. As I've told many other people who write me, the best thing to do for redness is to not look at it and leave it alone. Obviously, the doctor who saw you didn't think it was a yeast or fungus, so why should you worry? If yo have questions like these, the doctor who saw you is the one you should be asking....
Best.
