I've recently been diagnosed with bronchitis and had this persistent cough with thick phlegm. The doctor gave me some meds, and I'm feeling better now, but he suggested doing a PFT test if possible. Now, I'm wondering if it makes sense to just do the PFT test on its own, or should I also get a chest X-ray with it? Or maybe a CT scan of the chest would give clearer results? I'd love some guidance on what's best to do next.

Chest x-ray with pft is advised to the patient.
