[|AI|]  Thanks for your question on Chat Doctor. In my opinion you should first consult pulmonologist and get done1. Chest x ray2. PUT (Pulmonary Function Test). Chronic cough not responding to antibiotics can be due to bronchitis. So we need to rule out this first. And PFT is needed not only to diagnose but also for knowing severity of bronchitis.  And treatment is based on severity only. So PFT is necessary. Another possibility is chronic lung infection like TB or fungal infection. As routine antibiotics will not work on it. So chest x-ray is needed to rule out these. So better to consult pulmonologist and discuss all these.
