I have the same exact thing as you guys. I first started having vaginal burning 2 years ago almost exactly. I was on flagyl for a BV infection when it started. I thought it was just another yeast infectiion (which I got frequently). So tried the OTC, but it didn't touch it. This was a different weird kind of burning. The only thing the docs could find was strep b, so they kept giving me antibiotic after antibiotic trying to fight strep b, meanwhile making me worse and worse!! I ended up in the ER after about my 5th round of antibiotics. I had to come to the conclusion that I had systemic candida (yeast) that spread throughout my body. Along with the vaginal burning I had major depression/anxiety, severe acne and tons of other symptoms. My life has been a living for the last 2 yrs!!! I started trying to fight candida this January by starting the "candida diet" and from there have done tons of stuff trying to get rid of it, only to be constantly suffering with "die off" from the killing the yeast and stuff. I just had someone else on another board post to me explaining what the condition is:

There is a well known residual intracellular fungal infection that occur after an active infection caused by antibiotics. This infection is "dormant" candida that took hold inside the cells and deep in the tissues. It is a chronic atrophic erythomatous candidiasis. It is a not growing infection but still producing metabolic waste and toxins able to cause burning, redness, and inflammation. The treatment for that is long term systemic antifungal therapy plus anti-inflamatory/antifungal local creams.
Good Luck.

I don't want to go to the doctor again!! I do not trust them whatsoever. I think 96% of the doctors will not even acknowledge that candida is an issue or even know what it is!! I believe vulvodynia is the same as this problem, the doctors just wont admit it!! Please anyone post responses if they have figured out a cure for this.
