some people are more suseptable (sp?) than others. a fw years ago, I had a string of yeast infections that went on for about 10 months. I have no idea what finally worked for me. I do remember that the last time I treated it, I used a 7 day (monistat) one, instead of the 3 day one. My doctor told me that being on the pill could be a possible reason they kept coming back ( altthough I'm still on the pill now).
you should boil your underwear ( haha) or completely throw them out and just buy new sets.
and I'm pretty sure that sex doesnt have much to do with yeast infections. Although you can pass it back and forth to each other, it doesnt cause one. I think your confusing it with a bladder infection which can happen if bacteria make its way up the urethra during sex, and you don't pee afterwards.
The acidic balance of the vagina can be changed by your period, pregnancy, diabetes, some antibiotics, birth control pills and steroids. Moisture and irritation of the vagina also seem to encourage yeast to grow.
they are frustrating.. hopefully you'll find the cause and your doctor can help you find a treatment that works.
