What Is the Connection Between Post Nasal Drip and Sore Throat?
Post nasal drip and sore throat are commons symptoms of cold, flu and hay fever. When the sinuses oversecrete, the excess mucus drains down the throat. Some mucus clings to the back of the throat and causes irritation. The link between post nasal drip and sore throat is one of cause and effect. Under normal conditions, sinuses create mucus to control air moisture and capture particles in the air. Conditions such as illness; dust or allergens in the air, especially dry air; spicy foods; and even bright lights can cause an increase in mucus secretion. In cases of infection, the mucus might thicken and become opaque.
