Common cold
Sinus infections
Environmental irritants (dust, smoke)
Symptoms often include:
Frequent throat clearing
Cough (worse at night)
Sensation of mucus stuck in throat
When inflammation affects the nasal lining, mucus production increases — and gravity does the rest.
2. Acid Reflux (Silent GERD or LPR)
Gastroesophageal reflux disease (GERD) doesn’t always cause heartburn.
In laryngopharyngeal reflux (LPR), stomach acid reaches the throat and irritates the lining. The body responds by producing more mucus to protect the tissue.
Warning signs:
Chronic throat clearing
Hoarseness
Sensation of lump in throat (globus sensation)
Mucus without obvious cold symptoms
