Last month, my doctor diagnosed me with bronchitis because I was feeling congested and had thick mucus but I was?t coughing up mucus at all. I did?t have a fever. The doctor said my temperature was normal. My doctor prescribed me liquid azithromycin. I took it for 5 days. I went back to the doctor for a follow up and told them I still felt bad. The doctor listened to my heart and lungs said they sounded fine. It?s been weeks after that i?m starting to fill congested again and coughing with mucus stuck in my throat. My upper ,idle part of my back feels weird. I have no fever still, not coughing up any mucus, no chills. I?m really scared. I?m 19 with no underlying diseases. I?m going back to the doctor on monday.
