Taking Levaquin for pneumonia discovered through Xray as I had a nagging cough for a few weeks. Into 10th day of 14 day 500mg regimen and have had what feels like muscle tears in my calf muscle. First one happened after a weeks treatment during athletics and seemed to get much better in a few days. Second 'tear' happened today while walking. I can't really tell if these pains are muscle or tendon (achilles) but massage and heat helps. Sure am surprised to learn about all the side-effects from taking this drug and think I better end the treatment.
