There are many causes of foreign body sensation in the throat along with a particularly dry mouth, including sleep snoring, chronic pharyngitis, acute tonsillitis, etc. Generally, patients can do routine blood tests, laryngoscopy, etc. to determine the condition and treat accordingly. 1, sleep snoring: patients who snore during sleep may sleep with their mouths open at night, and the outside air directly stimulates the mucous membrane of the throat, which can lead to foreign body sensation in the throat and a particularly dry mouth. It is recommended to do sleep respiratory monitoring, and most patients can choose to wear a respirator for treatment. 2. Chronic pharyngitis: If there is chronic inflammatory reaction in the mucous membrane of the throat, inflammation stimulates chronic congestion and swelling of the mucous membrane of the throat, as well as lymphatic follicular hyperplasia of the tongue root, which may cause symptoms such as special dryness of the mouth and throat, foreign body sensation in the throat, and repeated throat pain. 3. Acute tonsillitis: caused by acute bacterial infection, which may lead to congestion and enlargement of the tonsils, causing foreign body sensation in the throat, especially dry mouth, sore throat, fever and other symptoms, can choose cephalosporins, such as cefuroxime tablets, cefaclor, or penicillin drugs, such as amoxicillin capsules for treatment. Patients with foreign body sensation in the throat along with a particularly dry mouth should pay attention to more rest, drink warm water to moisten the throat, and usually eat light and easily digestible food and avoid spicy and stimulating food to avoid aggravating the foreign body sensation in the throat and a particularly dry mouth.
