pneumonia
"While the side effects given makes a nervous-making read, I've been lucky in having no noticeable side effects.  On day 9 of 10.  Had gone to ER, felt like I was drowning, could not breathe well, not enough oxygen.  They put me on an inhaler to dilate bronchia, started me on Avelox, I got an Albuterol inhaler next morning.  Started feeling much better day 2.  Had a bit of coughing now and then clearing phlegm.  Only concern is how they tell pneumonia is actually gone, apart from symptom relief."
