I've had vaginal burning and have been tested for BV, Tric and Yeast and they all come back normal, as well as for UTI. It first started three months ago shortly after stopping breastfeeding and after having my wisdom teeth pulled. I ended up with nerve damage in my tongue from my teeth being pulled and still have a burning/numbness in my tongue
When the burning first started I had some discharge and assumed it was a yeast infection, I took Difuclan and it still didn't go away so I went to the doctor had a pap and he said to use canasten cream for 7 days. I did this and the burning went away. Two and half weeks later it came back. I assumed it was another yeast infection so this time I tried Monistat and took Difuclan again. I still had burning a few days later so I went to the dr to get tested for yeast again, he did a swab and it came back negative and he also told me my first test that I had done a month ago came back negative. Tested for UTI that came back positive and gave me Macrobid, this wasn't working so then I was put on Cipro, this also wasn't working so had a third test done for a uti that came back no infection and was told to wait to see what happens. Two days later I went bak to the Dr, did another test for UTI came back that I did have one, dr told me again to wait to see if it goes away on it's own. I went to another dr three days later and she tested me and it came negative for a uti but still put me on anitbotics Doxycline.
I've since been on multiple meds. First month it was only burning in my vagina, I then tried an OCT for Vaginal Dryness called Replens and it made it worse, it caused severe internal pain. Ever since then I have been dealing with burning or a rawness feeling or intense pain (similar to when you press on a pimple or wound) that comes for hours or days and then disapears then comes back. Wondering if it is hormonal (although I've been tested and they say they are normal)
