Share of Cost, One common cause of itchy throat is allergic rhinitis
Ehinitis or otherwise know as hay fever, may be one of the most common causes of an itchy throat. As many as 40 to 60 million Americans are affected by it.
Allergic rhinitis happens when the body overreacts to an otherwise harmless substance, releasing a chemical called histamine that causes these overreactions.
Common triggers include pollen, dander, dust, and irritants such as cigarette smoke or exhaust fumes.
