2. Cough variant asthma: It is bronchial asthma with chronic cough as the main or only manifestation, and if you suffer from this disease, you may have a bad cough for several months.
3. Chronic bronchitis: the clinical manifestations of this disease can be coughing, and the disease has a long, recurrent course. If the cough does not improve for several months, it may be caused by this disease.
