chlamydia infection
"Unfortunately I had to be treated for chlamydia twice with azithromycin due to bad choice. The first time I took the 2 500mg tablets and I didn't have any bad symptoms, the second time I was prescribed the Greenstone brand packet and it is HORRIBLE. I took it without food at first and went out to eat maybe 20 minutes later my stomach was very VERY upset! It happened maybe 5 minutes after I started eating my stomach felt like it had cramps way worse than a menstrul. I pooped somewhat but my stomach was still not in a good condition. "
