I took Levaquin last January. The day after I finished it, I had severe swelling of my ankles, knees and pain in my hip. I was unable to bend my legs. Prednisone reduced the swelling, but the pain in my hip continued. It is a year later and my hip is still extremely painful. I have had x-rays, an MRI and nothing shows other than a strain injury. I cannot walk up the stairs and when I am on my feet more than 15 minutes the pain returns. I have had injections and epidurals and nothing helps. Prior to the Levaquin, I had no problem whatsoever with my hip. I wear a TNS unit which helps, but nothing, even medication eliminates the pain.
