I went through that too. For years my cultures always showed up E-coli, bacterial vaginosis, staph aureus. Doctors always say Antibiotics will clear these up but they do not. Like what you are finding out, things just get more out of balance. The only way out is to work on the gut and then everything else will fall in place. It's hard...believe me, I know. I really did go through endless years of this crap. I used to scratch myself to pieces. It's awful :-(. No cream, Antibiotics , whatever will give any relief. Only getting re-balanced will resolve it. Some folks here have menitoned getting some slight relief from cultures vaginally, or placing a clove of garlic in there for a while ( Jhan I think has done that ) but that never helped me any.
