I just recently went to a Planned Parenthood to talk to yet another gynecologist about my vaginal infection nightmare. I explained to her everything; I had bv and yeast back and forth for about 2 years and haven't truly been cured of it for the entirety of my struggle. I've tried everything from antibiotics (orally and vaginally. Lots of them), drinking baking soda water, boric acid suppositories, using garlic suppositories, to taking acidophilus and folic acid supplements. Some of these things kind of helped, but didn't really fix the problem, or even make a huge difference.
Luckily, I had an appointment with a very kind and smart gynecologist that caught onto something other obgyns and doctors did not. It turned out that I had a yeast infection, big surprise, but I also had something called trichomoniasis. Trichomoniasis is an STD, but it often doesn't show symptoms. If it does, it may be similar to a yeast infection of bv. You can get more information about trichomoniasis here: http://www.cdc.gov/std/trichomonas/stdfact-trichomoniasis.htm
The reason why she saw I had trichomoniasis and the other doctors didn't is because she didn't let the culture she gathered from my vagina dry on the slide. She immediately swabbed me and put the culture on the slide and went to go look at it. In that order. She told me that if the culture is left to dry, the trichomoniasis will die, and thus, not be seen.
So the trichomoniasis diagnosis has been a big step, I think. I am positive this will make it easier for me to be cured of this constant infection I've been struggling with. Just as an fyi, I was treated with a "megadose" of metronidazole (4 pills in one day, instead of one). And I was also given fluconazole for the yeast infection. I've just now taken the medication, so I have no update on progress, but I will post soon enough to follow-up how successful my treatment was.
If anyone has any questions about some of the other treatments I've tried, or about anything regarding this post in general, feel free to comment. I want to help as many women as I can- I know how frustrating this can be.
