Prescription painkillers symptoms and conditions

In July 2007, I was put on Levaquin for pneumonia. I was 53 years old, working full-time, active. The pneumonia was caused by aspiration when vomiting. I had never had these problems - pneumonia or aspiration - before. I had gradually worsening generalized joint and muscle pain and stiffness, which I reported to my doctor after about 5 days on the Levaquin. The pain I was experiencing was worse than the pneumonia symptoms (mostly high fever). The course of levaquin was supposed to be 14 days. After 9 days, I could not tolerate it any longer. My doctor put me on a Z-pack (azithromycin) for the remainder of my treatment. It is a year later, and I am still plagued with muscle pain in my back, shoulders, arm, abdomen - and, at its worst, my legs. The only way I'm able to function is on prescription painkillers, which I detest having to take - but they're a lifesaver. I've been seeing a rheumatologist since December '07. He dosen't seem to believe the levaquin - pain connection. He thinks I may have Polymyalgia Rheumatica. I have consistently elevated blood levels of creatine phosphokinase, a muscle enzyme which indicates muscle damage. I was on prednisone 10 mg. from early March '08 which I have just weaned off of after suffering a depressive episode with a suicide attempt at the begining of this month. I can't work now. I'm terrified of becoming permanently disabled. Finding answers has been very difficult but I firmly believe that the Levaquin started all this.
