pneumonia
"'Came down with what seemed like a bad bout of influenza on a Friday night. Absent from work Monday, and Tuesday.  Wednesday and my cough is dry, chest heavy, gurgling sound in my chest. I thought it was wheezing, but that sound didn't go away even after inhalers.  I regret returning to work on Wednesday, but I've used up my sick time. Doctor gave me Rocephin on Thursday morning. By Thursday evening, I'm feeling good enough to be bored and wanting to return to work!  The creators of this medicine deserve Nobel Prize!"
