If indeed you have Cytolytic vaginosis, my assumption is that you had a milder case of it which was misdiagnosed as a yeast infestation since this is perfectly normal and happens more times than not. Then after taking high doses of probiotics, kefir, etc. the condition would naturally grow worse.
Cytolytic vaginosis is quite different from other vaginal conditions because it isn’t an infection but rather a condition of which the cause is not known for certain but only suspected of being an imbalance of hormones as well as an imbalance of the ecosystem of the vaginal environment. It’s speculated that actual causes of “whatever the cause is” – are actually products and situations such as contraceptives and IUDs, pregnancy, abortions, sexual intercourse and hygienic products since these are all capable of changing the environment.
The fact that you described the symptoms as being better during your period also leads me to believe your problem is Cytolytic vaginosis. This is because menstrual fluid is “basic” which means that the abnormal, over-acidic pH of the general environment during Cytolytic vaginosis is higher during the period than othewise.
If you’re able to find the ‘right’ doctor, he should know to test a sample of the environment via microscope. If it’s CV, he’ll see that the epithelial cells have lactobacillus attached to them as well as unclear cell membranes.
One possible way of finding out whether or not CV is your problem would be to stop all antifungals and probiotic sources. If your problems/symptoms grow worse rather than staying the same or getting better, then my guess is you have a yeast problem instead of CV. However, if the symptoms actually lessen, the there’s a good chance that CV is the problem and probably was all along.
The only treatment I’ve read about and the only one that actually makes sense is to simply raise the pH balance of the environment.
