My husband was given Levaquin and Prednisone in April for a bad chest infection. The last day of Levaquin, his knees began burning. He has been suffering with pain and cramps from his toes all the way up his legs. It has been in his fingers up through his elbows. He has shaking in his hands. He had an abnormal EMG. He has intermittent low grade fever. He started having trouble swallowing a couple of weeks ago. He now has to go to speech therapy because his tongue muscles aren't working correctly. He had none of this UNTIL he took this medication. The doctor now finally feels it is as a result of taking the Levaquin. The prescribing doctor had the nerve to lecture us about NOT stating he was allergic to the medication because he would be in the hospital with an infection otherwise. We are not returning to this doctor.
