Post-influenza sequelae

Could it be a sequelae after catching the flu the week before last?

I keep having a lingering cough.

I stopped taking the ENT medication after continuing it.

Shall we go to internal medicine?

I'm worried because my lingering cough has lasted a long time; should I also get a chest X-ray?

I guess I have a weak bronchial tube.

Even after contracting COVID-19, a lingering cough lasted for over a month.

At this time, I stopped taking ENT medication because it wasn't working, and after a while, I started having a lingering cough.

Ah, it's really exhausting.
