Sinus Drainage, Throat Mucous, & Postnasal Drip

Postnasal drip occurs when mucus from your nose and sinuses drains into your throat, causing symptoms like throat clearing, coughing, and a coated or irritated sensation. While postnasal drip is often associated with allergies, colds, or GERD, the presence of purulent (thick, discolored) mucus can be a sign of sinusitis, particularly if it’s accompanied by facial pressure, nasal congestion, or a reduced sense of smell. Left untreated, postnasal drip can lead to complications like chronic laryngitis, with persistent throat irritation or voice changes.

Treatment varies depending on the cause. For sinus infections with purulent postnasal drip, options include decongestants, nasal irrigation, or in some cases, antibiotics. Allergies may respond to antihistamines or nasal sprays, while GERD-related symptoms may improve with acid reflux management. If symptoms persist, especially purulent mucus or signs of chronic laryngitis, a thorough evaluation can help identify the underlying issue and guide effective
