I Was Diagnosed With Acute Bronchitis And Was Given Prednisone.

i was diagnosed with acute bronchitis and was given prednisone. i have taken all the med and now my coughing and congestion is coming back and its getting hard to breath again . the er doctor told me that my xray showed early stages of pneumonia but my labs were ok. do i need to see a Dr again or is the cough just going to last a while?
