Suggest Treatment For Cough, Yellow Phlegm And Breathing Difficulty For Three Weeks
You need PFT to rule out bronchitis.
Detailed Answer:
Hi,
.
First of all no need to worry for lung infection (pneumonia) because your chest X-ray is normal.
Your symptoms are also commonly seen with bronchitis.
So better to consult pulmonologist and get done clinical examination of respiratory system and PFT (Pulmonary Function Test).
PFT will not only diagnose bronchitis but it will also tell you about severity of the disease and treatment is based on severity only.
You will mostly improve with inhaled bronchodilators (formoterol or salmeterol) and inhaled corticosteroid (ICS) (budesonide or fluticasone).
Quit smoking if you are active smoker.
