hi there, dry cough
in a smoker is quite common due to bronchitis
, your blood counts are not abnormal. It is good that you have decided to quit smoking
, for now it just looks like nothing serious and a course of antibiotics should take care of your infection if any. It could be a viral infection, or just irritation to your bronchus
due to the smoking. Doesn't appear to be pneumonia
and so relax. If your symptoms do not subside even after this line of treatment then a repeat x-ray may be taken and you can get your sputum analysed for gram staining and cytology for any malignant cells ,for now this treatment is fine, take care.
