Painful swallowing in the throat may be caused by foreign body in the throat, acute simple pharyngitis or tonsil cancer, which need to be treated with medication or surgery. 1. Foreign body in the throat: when there are sharp foreign bodies in the throat such as broken bones and fish splinters, it will cause swallowing pain, which may be accompanied by a small amount of bleeding, and it is recommended to consult a doctor to take out the foreign body in time. 2. Acute simple pharyngitis: acute inflammation of the pharyngeal mucosa will cause mucosal edema or local tissue pain, resulting in pain when swallowing. Application of antiviral drugs, such as virus azole, acyclovir, etc.; oral laryngeal tablets, such as watermelon cream throat tablets, iodine throat tablets and lysozyme tablets, etc., the Golden Throat Pills and Tetrachromatic Tablets can be used; proprietary Chinese medicines, such as Liushen Pills and Throat Pain Relief Pills, etc.. In addition, 1%~3% iodized glycerin and 2% silver nitrate can be used to smear the swollen lymphatic follicles in the posterior pharyngeal wall, which has anti-inflammatory effect. 3. Tonsillar cancer: Early symptoms of this disease include discomfort in pharynx, foreign body sensation, sore throat on one side, which is more obvious when swallowing, and it has not attracted much attention. In the late stage, the pharyngeal pain is aggravated, causing reflexive earache on the same side, difficulty in swallowing, slurred speech and dyspnea. Different therapeutic measures are taken according to the extent of the lesion and the type of pathology. For some sarcomas, malignant lymphomas and undifferentiated carcinomas which are sensitive to radiation, it is appropriate to use radiation therapy, and cooperate with chemotherapy and immunotherapy at the same time. For early tonsil cancer, tonsillectomy is feasible, and for those with neck lymph node metastasis, neck dissection should be performed at the same time, supplemented with radiotherapy and chemotherapy after operation. If pain in swallowing occurs, it is recommended to consult doctor in time, make clear diagnosis, and carry out treatment under doctor’s guidance.
