Has anyone ever put the connection to their fibro. to the fact that they took an antibiotic in the fluoroquinolone class? I ask this because the symtoms can be almost identical. These antibiotics have fluoride in them also. These antibiotics are: cipro, levaquin, avelox, floxacin, and a few others that all have the same long lasting (years) side effects. If you have taken an antibiotic in the last few years before you started to get fibro. then it is possible that you had a reaction. Just google in the anti. you took and look at the side effects. It might be what is causing you problems.These Fluoroquinolones are very hard on the muscles and tendons amongst other things.
