Hi, your symptoms could be due to a post nasal drip, which can cause a chronic irritation in the throat
. This could be due to a sinus infection
, a cold or a chronic allergy. It could be sinusitis, if it is accompanied by nasal stuffiness and facial pain or pressure. Post nasal drip could also be due to allergens. These are substances like pollen, dust, animal dander, certain foods, insect venoms and certain medications.
