(Concern) The lingering cough from the cold is lasting a long time.

(Concern) The aftereffects of the cold last a long time. When you have a cold, the symptoms ease, and after a few days, the cold disappears, right?

But I also have rhinitis, so when I catch a cold, the aftereffects last a long time. I can't stop coughing even after the cold has passed.

I feel like I should find and eat foods like bellflower root that are good for coughs. I want to avoid lingering cough after a cold.

How can I improve my immunity? These days, when I cough, I feel self-conscious for no reason.

I'm struggling and worried because I have a lingering cough that lasts a long time after having a cold ㅠ
