Hi friend,
With the question “The persistent cough persists, what to do? ", the doctor would like to answer as follows:
Cough with itchy throat, sometimes wheezing for a few months, so pay attention to the common causes as follows: Chronic diseases of the nose and sinuses in general such as chronic sinusitis, Allergic rhinitis, exudative rhinitis, ... leading to posterior portal syndrome causing abnormal discharge of fluid from the nasal sinuses into the throat, causing throat irritation and coughing. Chronic pharyngitis, gastroesophageal reflux disease, chronic bronchitis, asthma,...
In general, to accurately determine the cause, you must visit a doctor directly. However, in the current complicated COVID epidemic situation, you can use the form of telemedicine that is most suitable for you.
If you still have questions about persistent cough, you can go to a hospital of Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wish you a lot of health.
Best regards!
