I received Levoquin for a bad sinus /respitory infection. I've taken full doses in the past, but no more. I took one 500mg Levoquin pill and within 1 hour I had a fever, uncontrolled chills, aching legs/feet and swollen hands. After finally falling asleep I woke up feeling better. I at that time didn't associate the two (have taken without side effects in the past). I just thought that I probably came down with some strange 24hr bug. I took my morning dose and wouldn't you know it the whole cycle started again. I haven't had a dose in 24hrs and just started taking Benedryl for some relief. My hands and feet are still swollen, red and painful. It hurts to walk b/c the soles of my feet are so sore and now I have signs of thrush. It is a nightmare. I will never, ever take this medication again!!!!
