Post nasal drip is triggered by the production of excess mucus that accumulates at the back of the nose. Some of the possible causes include cold, sinus infection, flu, allergies, pregnancy or deviated septum. If you have excess mucus running down the throat you will experience sore throat and cough. Heartburn or acid reflux can aggravate the condition. A proper diagnosis of the condition usually requires a detailed examination of the throat, ear and nose.
HOW IS POSTNASAL DRIP DIAGNOSED?
If the mucus enters the Eustachian tube (the tube connecting throat to middle ear) it can lead to a painful ear infection.
