Are you bothered by a sore throat and a persistent cough? 5 main causes
A feeling of a scratchy or ticklish throat without phlegm and then a persistent cough is a problem that bothers many people. The main causes of this are:
Allergies and air pollution: Inhaling dust particles, smoke, pollen, and pet dander can cause discomfort in the throat. This irritates the tissues in the throat and causes a persistent dry cough.
Acid reflux (GERD): Acid reflux can cause swelling in the throat. This is a major cause of a sore throat and coughing at night. It is also called laryngopharyngeal reflux.
Viral infections: A sore throat and cough can sometimes persist for weeks after a cold or flu has passed. This is due to a small swelling in the airways.
Asthma: In some people, the main symptom of asthma is a persistent dry cough instead of shortness of breath. This can be aggravated by breathing in cold air or exercising.
Dry throat and dehydration: Dryness of the mucous membranes in the throat due to not drinking enough water can cause a cough. Also, sitting in air conditioners for a long time can cause a dry throat.
