Levaquin and deep breath

I had cough for almost a month when I started to feel a light localized pain in the lower rib area, between the breast and the upper abdomen. ( when taking a deep breath or coughing).Then I was prescribed levofloxacin (levaquin) 500 for 10 days for a “supposed” pneumonia and sinusitis, no RX or lab tests done, by one pneumologist. Well, I felt others side effects but what really matters is that after 2 days taking the medication the pain worsen a lot, felt like a stab. I could not move in bed, was difficult to move, seat, get up, drive, work, whatever… In the fifth day I complained to the doctor who said I had muscular pain and the pneumonia was gone, but I should continue the 10 days treatment. So I did. After 7 days I felt when coughing that something was stretching and unsticking in the pain area. After the total disconnection the pain diminished a lot. Second week, back stabbing pain, third week front pain again, same type and disconnection, then diminished. Fourth week I felt something was loose , crackling in the area while driving or doing some movements. I also felt painful, loose knees and painful elbows. After many doctors, many exams and RXs done, now I know I had chronic bronchitis and costochondritis and I ended up with two ruptures of the costal cartilage, ( costochondral junctions ) 6ª and 7ª ribs, caused by levofloxacin. The RXs now show calcifications , body repairing the ruptures. I can not exercises now for 3 months. Ah…The sinusitis was back 2 weeks after stopping the medication. What I say now is: God protect us from some stupid doctors and these dangerous medicines !!!
