Levaquin and heart doctor

I took Levaquin as a treatment for pneumonia. After 3 days on the drug, all my joints were stiff and I had difficulty breathing. I called my doctor and I was told to continue the medicine. After a week, the reaction continued to get worse, I could hardly move, my breathing got worse and I had to be put on oxygen. My hands were like clubs and I couldn't open anything. I sat in a chair all day. It took me a half hour to get out of the chair to go to the bathroom. My hands were so swollen that I could not flush the toilet with my hands. I had to use my elbow to flush it. I saw doctors thinking I had rheumatoid arthritis. I saw pulmonary specialist and my lung capacity was at 48%. They sent me for many blood tests, cat scans, and I even had an MRI to try to find the cause. Finally, my heart doctor found out that some people were having adverse reactions to Levaquin. She found out that it caused severe anemia, breathing problems, and joint pain. She dosed me iron and within a week I was finally beginning to see the swelling in my hands start to decrease. I was out of work for 3 months.
