I took nine levaquin in late February, in treatment for pneumonia.  the tendonitis developed mid-treatment, got progressively worse. Only one tendon, left leg. It ruptured in early May. During surgery, considerable necrosis was discovered, which had to be scraped away. the remaining thinned out tendon was reconnected. I was unable to walk for ten weeks. Since then have again been able to walk, thankfully WITHOUT PAIN. I consider my surgeon a genius for having restored my mobility.

Only other ADR from levaquin was mouth sores, very painful, which at the time I thought was due to the inhaler I was using for pneumonia, but mouth sores persisted long after I stopped using inhaler. This has since cleared up. Considering what others have gone through, I guess I was lucky.
