Thankfully my mastitis cleared up pretty quickly, but despite taking a probiotic and trying to eat lots of probiotic rich foods, I've been feeling pretty awful since starting the antibiotic a week ago (which I stopped taking a few days ago with the doctor's blessing since I was feeling so yuck). Between an hour and two hours after I eat, I get horrible stomachaches and feel like vomiting. It tends to come quickly and only last an hour or so before going away quickly, but i feel pretty horrible. TMI, stool is also a bit looser than normal, but not to the extreme.

I haven't taken an antibiotic in like ten years, anyone else have this experience after taking an antibiotic for mastitis (or anything else) and have it resolve on its own, or do I need to be worried about seeing a doctor?
