bronchitis
"I woke up in the middle of the night after taking 3 doses (that's only 3 pills) in excruciating painit felt like someone had a huge sledgehammer and was slamming it against my left knee over and over again.  The pain was so bad I even vomited.  This pain lasted for weeks and I know have chronic tendonitis in that knee and am in constant pain.  Some days are better, but it's a constant pain and it's always swollen.  It's been like this since 2009, it is now 2016.  This class of drugs is toxic and should never be used as a 1st line of attack for infections; it shouldn't be used at all.  Don't ever take this drug or the others like it, they are called the "Fluroquinolones"  which also includes Cipro, Avelox to name a few."
