diverticulitis
"Cipro was horrible. I have never had a reaction to an antibiotic before. Mentally disturbed head. It was very strange and made me panicky. Broke out in a rash on forearms and itchy tight chest.  Read how awful this drug is. Thank goodness my reaction happened after a few doses and not a week or two. Flouriquinolones are poison for me. I never would have thought an antibiotic could be so harmful."
