Recurrent sore throat is often associated with chronic inflammatory factors in the throat and tonsils. Patients may use their voice excessively in their work and life, or they may smoke more, drink more, or eat spicy and stimulating food. Some patients may be exposed to air pollution for a long time in their work and life, which may cause chronic inflammation of the mucous membrane of the throat and lead to recurrent sore throat symptoms. Patients may have recent mental and emotional problems, as well as repeated fatigue, staying up late, and other factors, which may cause the body’s immunity to decline, and may also cause recurrent acute inflammation of the throat due to the invasion and infection of bacteria, viruses and other pathogens in the external air environment.
