I ran into someone tonight who swears his fibro was caused by Cipro. And I'm just curious if anyone has heard much about this? I can't remember if I was given Cipro before or after I got fibro, but it was definitely during those years. What really interested me was that his symptoms are so similar to mine. I've heard a little about others swearing they were harmed by Cipro, but haven't heard much about it in a long time.
