I am 51 years old, in January, I had a three day bout of 105.1 temp. Finally went to the doctor on the Friday it was down to 101.2. She gave me a zpack antibiotic. Since then I have been fighting a stuffy nose, green mucus barking cough. Went to the doctor in March she gave me an antibiotic and said my lungs sound clear. Since then I wake up every morning coughing up a very thick brown mucus, I still have a stuffy nose, I have to cough up phlem all day, I have a terrible barking cough deep in my chest, and I feel very tired. I went to the doctor she said it will work it's way out. I have been sick since January. I have never had allergies before so not sure what is wrong with me. Do I go to a different doctor.
