Please anything you can suggest is much appreciated!!! This is long but I want to make sure you know what's going on!

Since mid-October, I have been battling with what two doctors have diagnosed as your average yeast infection. THe first doctor said that it had been going on for a while adn so she had me on two topical meds-one to repair the slight tear that had been created by the infection and then one to get rid of the infection. Went back for a check up, was told I was all set, fast forward two weeks, a month...same problem.

I have the typical topical symptoms but none of the incredible itchiness, irritation, unbearable effects (I have had one once before and THAT one was bad- this is really different).

So, when I was visiting home, I went ot the same doctor I had gone to before and she said that under the microscope she could barely see anything but managed to pick upa tiny bit of yeast.
Now a one-time pill, gone in a week.
Fast forward two weeks...same symptoms.

Back to first doctor. Oh yes, definitely still same infection. With this one week topical med you will be all set!
Fast forward two weeks...same symptoms.

I have been using a white vinegar and water solution after showering. Cotton underwear. Barely any relations with my partner. We're talking four months with the SAME infection. THe only thing that is saving me is that it's not severe at all thank goodness.

Medicines aren't working. I don't eat lots of sugars and caffeine, etc. Vinegar is being used. Also, I know they say birth control can't really be a cause anymore but is that the case? I've been with the same partner for almost three years and have used the pill for just about all of it. I recently had to change from one generic brand to another but that was probably 97% exactlyt eh same. I'm thinking about stopping it to see if there are any changes but I never had this problem with the first one and the change was incredibly small.

WHAT DO I DO??

This is very frustrating and somewhat scary because I feel very impotent and don't know waht to do. The doctors swear up and down it's a yeast infection (they've done exams and my symptoms are the weird discharge and very slight irritation) but their meds aren't working. I've tried certain natural remedies and they're not working. It's not a normal case and I don't know what to do!!!
