Levaquin Achilles Tendon, Muscle Weakness, Triceps, Stiffness, Quads

I have just finished taking Levaquin for a 10day treatment for pneumonia. In the last 5 days or so I have noticed stiffness in my achilles tendon (no pain) until I get moving. I have also notice a tremor in my hands and no muscle weakness and shaking in my triceps and quads. Of course I hadn't read the precautions to this drug before noticing these symptoms. I contacted both my pharmacist and physician and neither seemed concerned and told me if I was really worried to go to the emergency room. I am wondering if these symptoms will disappear since I am no longer on the drug, how long it will take, and how long I should worry about tendon damage----is the possibility of rupture forever???
