Disappearing Lichen?

So I have had recurrent UTI for months. Landed in the ER with a fever at one point and multiple yeast infections. The skin around my urethra became inflamed and turned white. It would burn like crazy anytime I peed. Well here we are, a week and a half later and the white sections are pretty much gone and all that’s left is some sensitive raw skin. Could this still be Lichen? I have been tested for yeast and every STD under the sun, all negative.
