Hi, I've had this cough for a long time. About 3 1/2 weeks ago I had a random cough. After a Half a week, a cold came in so I thought I was experiencing post nasal drip. Then my cold stopped but the cough continued and got worse and worse. Louder, Harder, and started to become consistent. So I went to the doctors and they gave me an inhaler and anti-virus biotics because i showed symptoms of bronchitis and from there on my cough started to fade away. After using the whole bottle it is gone and the puffer had like 300 puffs on it. (No way i'm supposed to use it all) So after a week has gone by, the cough is returning and i'm coughing up phlem again. (MY first phlegm was like brown, then green, then clear) Now the phlegm is just clear but the cough is returning. What's wrong with me?
