I still have a cough as well. My bilobectomy was 6 months ago. My thoracic surgeon referred me to a pulmonologist and I have an appointment at the end of March. I know how you are feeling. I think my cough might be from GERD. I have noticed a lot of acid reflux since surgery that I never had prior. I’ve tried medications however and nothing has gotten rid of the cough. Mine is more persistent after eating and drinking.
