I was prescibed levaquin 500mg. 10 days for broncitis, day 3 I had severe leg and muscle pain, also severe swelling in my feet, I feel like I ran a 26 mile marathon!! also severe fatigue. I did not have any symptoms like this before I started levaquin in my life. pharmisist says this not one of the sideaffects!!!! I told him this is a relatively NEW drug so the jury is not in... I think the fda should do more tests on this drug!!!! hopefully leg pain and feet swelling will go away soon,but other people comments is not reassuring!!!
