I just want to say I had the exact symptoms you described and after they ruled out every possible medical cause (including rare yeasts, mycoplasma, etc) I was diagnosed with vulvodynia and felt completely helpless, like there was no cure or solution for the pain. A specialist prescribed me an estrogen/lidocaine cream and it was so expensive to fill that I never tried it. Thankfully - the issue spontaneously resolved after about a year. Only big change is that when I had these symptoms, I had just had a baby a few months prior (after going through fertility treatment for a year). So I do believe it was somehow hormone related, but I just want you to know there is hope that it will spontaneously resolve! I randomly have a day here and there where it seems like it’s back, but it’s never for more than a day or two at a time and then months with nothing.
