Deteriate symptoms and conditions

In July of 2005, I was prescribed 14 doses of Levaquin 750 mg for a bad case of viral pneumonia and mononucleosis. After two days of insomnia, I developed extremely painful feet, especially the bottoms of my feet. Last month (Aug 2007) I was diagnosed with Avascular Necrosis of the Hip, and just had my right hip replaced (total). At age 45, I am fairly young to have developed such an ailment and other than July of 2005, have been healthy and active my entire life. In retrospect, I am beginning to wonder if Levaquin caused my avascular necrosis, as the doctors are at a loss.

I have been on Prednisone for 27 years for Addison Disease. If you take more prednisone than needed for you system you will get the moon face, weight gain and even the shakes. My immune system is very low due to the medications, my legs cramp and make is very hard to sleep. I have found that after taking prednisone for so long, it will start to deteriate your muscles, blood vessels, bones and teeth. At this point I have no choice but to take this medicaiton as it keeps me alive. By the way, if you are on Prednisone too long your Adrenial glands will stop producing the steriods that your body needs. This medication is very hash. Please advise if any one else has Addison's disease and are taking medication other than prednisone for the illness. I feel for anyone that has to be on this medication.
