You really need to be able to recognize the onset of tendon injuries. As you can see on the board here, thousands have developed serious tendon injuries including tendon ruptures and severe tendinitis. Take a look at ****** -- there's lots of literature and studies showing that many takers of fluoroquinolones have suffered terrible side effects after just single uses. Let's get out the word so doctors and patients are fully aware before undertaking the risk fluoroquinolines pose. People need to be aware of this so they are able to take action (like getting to a doctor) before major damage sets in. Hope this helps.
