Hello and hope you are doing well.
Repeated episodes of dry cough or throat irritation could most probably be due to allergens. These are substances like pollen, dust, animal dander, certain foods, insect venoms and certain medications. Mold exposure can cause allergic symptoms. Exposure to allergens causes a runny nose with a resultant post nasal drip where secretions from the nose go backward into the throat and irritate causing cough. Cough is a protective mechanism by the body as it helps to prevent infections. Discuss these options with your doctor when you happen to meet him next time. In the meantime for relief from your symptoms you could do warm salt gargles and take OTC antihistamines.
Hope this helped and do keep us posted.
