Description

The mucous membranes of your upper respiratory tract (nose, mouth, and throat) are usually moist and smooth. This area can become dry, irritated, and sore when an immune system reaction to an allergen or infection triggers the release of histamines, leukotrienes, and other inflammatory chemicals that intentionally irritate membranes. As a result, sore throats are often a warning sign of an upcoming condition such as a cold or flu.

Symptoms and Signs:

As the name implies, a sore throat involves a painful throat that is further irritated when swallowing. The mouth and throat are dry and parched and the throat is likely inflamed.
