If the symptoms of dry cough are mild, you can first do home treatment such as wearing a mask, applying heat to the throat and choosing cough suppressants to cope with them. Some cough symptoms are obvious and last for a longer period of time and need to be treated separately for different types of dry cough, and generally acute subacute dry cough is taken as the main symptomatic treatment.
The ideal situation for chronic cough is to be able to go to a specialist clinic of the department to find the cause of the cough and do specific treatment for the cause, or to do empirical treatment according to the clue guidance.
