bronchitis
"I am over 60 years old, have afib with medication, have rheumatoid arthritis on medication.  I was given levaquin to take for bronchitis infections and ear infection previously treated with zpac.  I only took two pills, and had tendon problems in my legs so bad I could barely walk,  I quit taking immediately, it took a while to get over the pain in my legs.  I should never have been given it due to pre existing conditions and age."
