Chronic pharyngitis has milder symptoms and lasts longer in comparison with acute pharyngitis, and the complaints are usually solely about the throat. Yet, still there is more than one cause of chronic pharyngitis. Here are some of the most common ones:
Frequent Infection Of The Tonsils
This is probably the most significant cause of chronic pharyngitis, which occurs more often when frequently exposed to cold weather and flus.
Throat Irritating Factors
These factors are almost as notorious as viruses. Some of them are smoking, alcohol, dry and dusty air, smoking, air pollution, post nasal drip and very hot or cold food and beverages.
One of the newer causes of chronic pharyngitis, which is still undergoing a great deal of research, is the inflammation in the esophagus (swallowing tube). It is considered an allergy-like inflammation, which is probably caused by food.
It is basically the travelling of the acid made in the stomach up through the esophagus and to the throat. If this situation is not treated, one of the results is chronic pharyngitis (sore throat).
Although it may sound frightening, a sore throat with the symptoms of chronic pharyngitis, which lasts more than a couple of weeks can indicate a serious illness such as AIDS or throat cancer.
Nasal obstruction or congestion is a partial or complete blockage of the air passages, which start at the nostrils and end in the throat. No matter what the cause of this congestion (deviated nasal septum, nasal polyps, rhinitis, etc.), it may lead to the irritation of the pharynx.
Hay fever, which is an allergic disease caused by grass, weed or tree pollens and also known as allergic rhinitis, is also among the many causes of chronic pharyngitis.
