How do I get back to having a healthy hooha?

So ive been dealing with these symptoms for like 6 months now and im at my wits end i cant have sex or even do myself, I noticed my downstairs was burning and I didn't know why I washed with water (ive never used feminine washes or anything) well it went away by next day so I never thought anything of it well I hooked up with a guy and boy did the burning come back with a vengeance i didn't have insurance so I dealt with it hoping it would just resolve.. it didn't. It would wax and wane (it was just the burning at this point no real smell, no unusual discharge just very uncomfortable) well fast forward and well the burning was minimal usually but a fish smell crept up on me plus a crawling feeling in my clitoral region sometimes it even felt like a hair was stuck and stabbing me up in there (when I say uncomfy was an understatement) I finally went to the dr they tested me and I tested positive for bv and ureaplasma I finally had some answers, well they treated the bv with metronidazole gel but never addressed the UP. Just told me to complete treatment and add a vaginal probiotic. And hey it worked for a while I was more comfortable but bv came back and it came back like it owned the place. I just completed another round of metronidazole gel but the burning is now back and I just idk what to do now. Its like I trade one symptom for another. I never had issues down there except one yeast infection as a teen and I just want to get back to being ok again.
