Part of the sore throat is caused by acute infection caused by viruses or bacteria invading the mucous membrane of the pharyngeal cavity, which is mostly caused by cold or flu, with rapid onset and severe pain. The other part is due to chronic inflammation caused by long-term stimulation of smoking and alcohol, irregular diet, and disorder of work and rest time, etc. These patients have a slow onset, and the pain is not severe, but they have been suffering from the disease for a long time. It is also recommended that patients with a long history of smoking and drinking should undergo laryngoscopy at a regular hospital every year to rule out the occurrence of laryngeal tumors. Some patients have inflammatory diseases of the thyroid gland, mostly accompanied by painful pressure on the thyroid gland, such as subacute thyroiditis, and are advised to visit general surgery, endocrinology and other related departments.
