Ihave been taking levaquin for 9 days for the last week I have experienced severe aching in my feet and up my calves, I have trouble sleeping at night because my feet and legs throb all night! In the morning it is a little better and then it starts all over again all day long. I had one day left of my medicine, when I found this website, I will not take any more. I advise other people do not take this medication!!!! Thanks for all the info from everyone on this website.
