Symptoms of acute laryngitis include hoarseness, cough, phlegm, and pain or discomfort in the throat. Acute laryngitis is an inflammatory reaction caused by overuse of the vocal cords, or irritation or infection of the vocal cords. Acute laryngitis can be triggered by inhalation of harmful gases and dust, or by fatigue and other factors that lead to a decrease in the body’s immunity. The main manifestations of acute laryngitis are hoarseness, complete loss of voice in severe cases, laryngeal pain or discomfort, difficulty in swallowing, accompanied by fever, cough, sputum and other symptoms. In children, the main manifestations are hoarseness, barking cough, inspiratory laryngeal stridor and dyspnea, and untimely treatment can cause respiratory failure or even death. If you have throat discomfort, it is recommended that you consult a doctor for standardized diagnosis and treatment in a timely manner.
