Suggest Remedy For Pneumonia With Cough, Runny And Stuffy Nose

Hi, i was diagnosed with pneumonia about 5 weeks ago. Doctor put me on Levaquin for ten days, and saw no improvement. I was re-xrayed and doctor said my lungs were clear again, but i was still sick and saw no difference in my health, so he put me on augmentin for 10 days. Finished the augmenting prescription still haven't noticed a single difference in my health. Still have a hacking cough with phelgm being brought up, runny and stuffy nose with yellowish mucus, nasal congestion, and sore throat. What should i do and what could i possibly have?
