The pains felt like my upper intestines were on fire, with a particular focus on my left side, I'd say in the area between the bottom of my rib cage and where a kidney would be.
The stuff has STILL tarnished my taste for anything with oregano in it

We tried a pork tenderloin the other night with a homemade marinade of chopped oregano and sage, and just the smell of it in the kitchen made me sick to my stomach.
I just had a yeast infection from a round of antibiotics, nothing long term or chronic. My symptoms were vaginal itching and abnormal discharge. The OTC yeast creams (Monistate, etc) gives me a horrible reaction, often worse than the yeast symptoms themselves, so I decided to try the health food store.
What my physician ended up prescribing me (over the phone, since I'd just finished the antibiotics he'd written for me) was Diflucan. One pill, infection cleared up.
