Post-nasal Drip Associated With Sinusitis

What Is a Post-nasal Drip?

Post-nasal drip is defined as the dripping of mucus from the nasal and sinus passages down the back of the throat. It is a common health condition affecting males and females equally and is becoming increasingly prevalent in our society. The common causes of post-nasal drip may include allergies, asthma, viral infections (including the common cold), eating spicy foods, deviated nasal septum, irritants in the air (such as fumes or dust), pregnancy, medication, acid reflux, neurological inflammations, and sinus infections.

Post-nasal drip can also be caused due to sinusitis. It can be the only symptom of sinusitis, or it may have other symptoms, like nasal congestion, facial pain, and colored nasal discharge.
