2. Bronchitis is an extremely common respiratory disease. At the initial stage, it often shows symptoms of upper respiratory tract infection, such as nasal congestion, runny nose, sore throat, hoarseness, itchy throat, irritating cough and retrosternal pain. There is not much phlegm in the early stage, but it is not easy to cough up. After 2 ~ 3 days, due to the increase of inflammatory secretions, sputum can turn into yellow pus.

3. Cough variant asthma is a special type of asthma. Generally, there is no obvious asthma, but it is characterized by repeated intractable cough, mainly dry cough, which is more common at night. Many patients are accompanied by itchy throat, which is often induced by catching cold, exercising and inhaling cold air, and may also be caused by contact with pollen, dust and certain foods.

4. Post-nasal drip syndrome Due to nasal diseases such as rhinitis, sinusitis and nasal polyps, secretions flow back to the back of the nose or throat, or back to the glottis and trachea, causing foreign body sensation in the pharynx, dryness and itching of the pharynx, frequent throat clearing, blockage and adhesion of the pharynx, and often accompanied by chronic cough.

5. Gastroesophageal reflux disease Gastric contents such as gastric acid reflux to the esophagus and invade the pharyngeal mucosa, causing acute pharyngeal injury, pharyngeal itching and repeated chronic cough. Some people don't have acid reflux hiccups. Cough is the only symptom. Therefore, chronic pharyngitis and tracheitis are easy to treat.

There are many reasons for itchy throat and cough. The first is to find out why. If it is caused by external environment, you need to leave the environment that causes cough. In foggy days and windy and dusty days, you should go out less, wear a mask, don't smoke, stay away from second-hand smoke, don't drink hard liquor, and don't eat spicy and salty food. If it is pharyngitis and bronchitis caused by a cold, drink as much water as possible, use some antitussive drugs, and use antibiotics when complicated with bacterial infection.
