First of all, we should clarify the causes of foreign body sensation in the throat. The more common causes are pharyngitis, epiglottis cyst, pharyngeal polyp, and even early cancer. Pharyngitis is mainly a hyperplasia of the mucous membrane and submucous lymphatic tissue in the throat, and this foreign body sensation needs to be treated with some Chinese medicines to clear heat and dispel fire. The other thing is to abstain from spicy and irritating food, smoking and alcohol, the treatment of pharyngitis is a long-term process, prone to recurring attacks. Epiglottis cysts and pharyngeal polyps are caused by long-term inflammation stimulating the pharynx, and the foreign body sensation caused by them needs to be treated by surgical excision, which is usually curable after excision. Early stage cancer is hidden and requires detailed examination by an ENT specialist.
