Hello, I am in day three of taking zpak. I have alot of mucus in my nose and lungs. I am constantly coughing, I am weak, and my lungs are starting to burn. The doctor at Urgent Care called it bronchitis, and asked if I had ever had pneumonia. I am taking cpugh syrup and using an inhaler. My question is, after Thursday when I am done with my meds, if I am still this sick, should I go to the hospital, urgent care again, or just be patient?
