Hi, I Have Had Pneumonia For 9 Days Now, And

Hi, I have had pneumonia for 9 days now, and I have been taking Levaquin for the 9 days I have been sick. I was given a ten-day supply of the antibiotic, but given that I'll be taking my last pill tomorrow and that I still have symptoms of pneumonia (coughing up phlegm and feeling congested) it doesn't seem too promising. What would you advise I do?
