What is Post Nasal Drip?Post-nasal drip describes the drainage of mucus secretions from the nose or sinuses down the back of the throat.
Glands in the nose and throat continually produce mucus (one to two quarts a day). Mucus moistens and cleans the nasal membranes, humidifies air, traps and clears inhaled foreign matter, and fights infection. In normal conditions the mucus is normally swallowed unconsciously, the feeling of it accumulating in the throat or dripping from the nose causes post nasal drip or drainage.
The symptoms usually get better within 10 days.
The diagnosis is based on the symptoms, a thorough examination of your ears, nose and throat as well as a review of medical history of the patient. In very rare cases x-rays and CT scans may also be performed to confirm the diagnosis.
