Was prescribed Levaquin in November 2008 for suspected pneumonia, then 5 other times until last week. I've had really bad knee, thigh and arm and shoulder pain for the last 2 months. My legs get so weak and painful that getting out of a chair makes me want to cry, i've got to the stage that i need to hold on to something just to get on to my feet. My arms are rather weak, i can't even lift a small 10lb box without pains shooting down my arm. I've since stopped my last prescription of Levaquin 750mg daily for 7 days, the pain seems to have eased a little but not enough. My pulmonologist keeps prescribing Levaquin each time i catch a cold or have shortness of breath. I was also taking 60mg of Prednisone from November 2008 until March for newly diagnosed Lung Disease. I've complained to him more than once about pain and weakness in my legs etc. He keeps telling me my muscles are deconditioned. I've now started physical therapy and i'm doing aqua therapy, so we'll see if this works or not. Maybe it will also help my restless legs, which seems to have intensified this past few weeks.
