Help!! So a couple of weeks ago I was put on an antibiotic for a sinus infection. The literal LAST day of treatment I suddenly got a really bad yeast infection. Unlike most of my yeast infections this did not come on slowly and gradually worsen, this was a full blown yeast infection overnight. Luckily I had the DR write a script for diflucan knowing my history with yeast infections. I was out of town and didn't have it with me so I took it the following Monday late at night (this was last Monday) then Thursday night I took another dose. By Saturday and even more so yesterday I was feeling a lot better- finally! (I'd say 80-90% back to normal) so my partner and I had intercourse. I peed and cleaned immediately after but today I am experiencing itchiness and pain again. Please help. What do I do?! Also- I've been tested for everything else it could be and so has my partner!

Some backstory: over the summer I had the worst yeast infection of my life it literally took a month to heal and even after that sex was really painful and terrible for almost another month afterwards. I am terrified of this happening as it put a huge damper on our physical and emotional intimacy. I don't know WHAT to do. This is so miserable and discouraging.
