Whenever the seasons change, do you wake up every morning with a runny nose, struggle to breathe through nasal congestion, and keep coughing from mucus dripping down the back of your throat? When others seem completely fine, it can feel especially exhausting to go through it alone. Perhaps you wondered if it was a common cold, only to feel frustrated when cold medicine brought no relief.

Do you feel like your cold is completely gone, yet you are still stuck with a persistent cough? Do you have trouble falling asleep at night because something feels like it is dripping down the back of your throat, or find yourself clearing your throat and sniffing without reason during the day? That exhausting dry cough might actually be caused by this condition rather than a lingering cold.
