If there is a sudden foreign body sensation in the throat, first recall if you have eaten fish or bones, visit the hospital and give a tongue depressor, indirect laryngoscopy or electronic laryngoscopy to rule out the possibility of a foreign body. If there is no foreign body present, it may be caused by chronic pharyngitis, which is produced by acute inflammation and repeated episodes of irritation. Lymphatic tissue and lymphoid follicular hyperplasia may be evident, resulting in a foreign body sensation in the throat, which is apparent when swallowing. The treatment can be a light diet, avoid smoking and drinking alcohol, avoid spicy and stimulating food. You can also take Chinese medicine preparations with anti-inflammatory, anti-swelling, pharyngeal, and antipyretic effects to treat pharyngitis, such as Slowlime, Luk Shen Wan, and Gamboge Bing Mei Tablets. If the lymphoid follicles and lymphoid tissues in the pharynx are large, they can be removed by surgical ablation.
