pneumonia
"I had pneumonia and was given a 5 day treatment of Zithromax which didn't help, followed by a week of Biaxin which again didn't help.

After the second day of Avelox I felt a twinge in the tendon of my thumb that I put down to an injury a couple of weeks prior - but I have since read could be a side effect.  I have had zero appetite and been forcing myself to eat - no nausea, just no appetite which is probably a good thing for me.  Minor issues with concentration - trying to avoid driving, but since I don't feel well enough to go out yet (just took 6th dose of 10) it is not really an issue.  The symptoms of the pneumonia/bronchitis are improved when I wake up, but still present when I get into daily activities."
