The throat diseases that cause sore throat mainly include acute epiglottitis, pharyngeal tonsillitis, pharyngitis, laryngitis and laryngeal cancer. Especially pharyngolaryngitis, is the main cause of sore throat. Due to the local inflammation of mucous membrane and submucosal tissue in the throat, the pain nerve is stimulated, which leads to pain symptoms, which are often aggravated when eating or swallowing. In addition, when the tumor cells of laryngeal cancer have deep infiltration, symptoms of sore throat may appear.

2. Other diseases

Common diseases that can cause pain in the throat include colds, rhinitis, oral ulcers, palatine tonsillitis, glossopharyngeal neuralgia, myocardial infarction and other non-throat diseases. Infections near the throat, such as upper respiratory tract infection, can involve the throat and cause sore throat. The pain symptoms of glossopharyngeal neuralgia are severe, and most of them are unilateral pain; Throat pain caused by myocardial infarction is often accompanied by palpitation and chest tightness.

3. Non-inflammatory stimulation

Growling loudly, singing for a long time and other factors, or eating too much melon seeds, can cause congestion and edema of capillaries in the throat, leading to non-inflammatory pain in lymphatic tissue. This kind of pain is generally not very severe, and it can be quickly relieved by drinking more water, eating lightly and paying attention to rest.
