Why does chronic pharyngitis cause coughing? The symptoms are like this

In everyone's impression, chronic pharyngitis causes itching, but in fact, there are many other symptoms, and cough is the most common. This kind of cough is medically called "pharyngeal cough" or "laryngeal cough". The treatment should target the inflammation of the pharynx and throat, eradicate the cause, and use appropriate cough suppressants.

Coughing is a protective reflex function of the respiratory system, a rapid and forceful exhalation movement. You start by taking a breath, then the glottis closes and the soft palate rises to partially or completely close the nasopharynx. The chest and abdominal respiratory muscles contract and the pressure in the lungs increases. When it reaches a certain level, the glottis opens suddenly, and a strong airflow quickly passes through the narrowed airway, impacting the glottis, making a coughing sound, and expelling secretions and foreign objects from the respiratory tract. The sensory nerve endings involved in the cough reflex come from the trigeminal nerve, glossopharyngeal nerve, vagus nerve, superior laryngeal nerve, etc. These nerve endings are very sensitive to foreign objects, touch, cold, heat and chemical stimulation, and can cause coughing once they are stimulated by inflammation.

In acute or chronic pharyngitis, the pharyngeal mucosa becomes congested, edematous, proliferative, thickened, or has secretions attached. These inflammatory responses stimulate sensory nerve endings and can produce a reflex cough. Patients often experience bouts of coughing due to itching, dryness, and a foreign body sensation in the throat, which is sometimes a dry cough and sometimes produces a small amount of sticky phlegm. If acute or chronic pharyngitis affects the laryngeal mucosa, the cough will become more obvious. Severe coughing can cause throat pain, mucosal bleeding, and flushing and tearing of the face. This type of cough is medically called "pharyngeal cough" or "laryngeal cough". Treatment should target the inflammation of the pharynx and larynx, eradicate the cause, and use appropriate cough suppressants, such as 25 mg of Kebiqing, 3 times a day, or the Chinese medicine Chuanbei loquat cough syrup.

It should also be noted that some patients with acute pharyngitis are prone to complications of tracheitis, bronchitis or pneumonia due to their weak constitution, poor resistance or severe infection. The cough becomes more severe, the voice becomes dull, and the secretions increase. As the condition worsens, the sputum may become clear, sticky white, or thick yellow. Systemic symptoms are obvious, such as fever, headache, chest tightness, chest pain, increased white blood cell count, abnormal X-ray or film, etc. It is necessary to go to the hospital for diagnosis and treatment as soon as possible and give sufficient antibacterial and anti-inflammatory drugs to avoid worsening of the condition.
