I was prescribed Levaquin a couple of years ago and I thought that I was crazy. During the time I took the drug, I felt this horrible sensation in my leg as kind of like the feeling when your leg has fallen asleep and it's coming out. It was a horrible tingle that just persisted to the point where I thought I was going crazy. I had to call an ambulance becuase I couldn't take that intense feeling any longer, people were telling me that I was delusional but now I find out after reading on this site that it had to be the Levaquin. Recently I was prescribed Levaquin for a sinus infection and I have the worse lower back pain I have ever experienced in my life. I couldn't figure out why I was having so much pain not only in my lower back but throughout my loints and now I realize that it was the drug. I will never usr levaquin again.
