Levaquin and albuterol

I was prescribed Levaquin 1000 mg. for 5 days for pneumonia the last week of December 2006. I was also prescribed Prednisone. Everything I ate tasted like metal. A couple of days after I started taking the Levaquin I started experiencing muscle cramps in my rib cage which are so severe it makes me double over in pain. After more than a year I still have the muscle cramps which now include not only my rib cage, but the arch of my feet and sometimes legs. I have a torn tendon in my left arm which didn't happen until about a month ago, but I am sure it is caused from muscle damage from the Levaquin. I am also on Advair Discus 250 which I didn't take before using the Levaquin. I didn't require inhalers or other medication before the pneumonia. My doctor now says I have COPD caused from asthma and chronic bronchitis. I used an Albuterol inhaler when I first got sick because the pneumonia was so bad. I thought after taking the Levaquin I would get back to normal. But even after the infection was cleared up I would get out of breath, so I returned to my doctor. She did an x-ray and said I had COPD and prescribed the inhalant. What I don't understand is that I didn't have breathing problems before the Pneumonia. I didn't have joint pain and muscle cramps either. I have had to quit working this past year because of it. I cannot go without the Advair, I can no longer walk long distances without pain. I have constant muscle pain just trying to do normal housework. How long do the effects last? Must be a lifetime.
