I can understand your concern. Since you are asthmatic, your continuous coughing is mostly due to acute exacerbation of asthma. And best treatment for this is inhaled treatment and you are not taking it so you are not improving. So better to consult pulmonologist and get done 1. Clinical examination of respiratory system 2. PFT (pulmonary function test). PFT will not only diagnose bronchitis but it will also tell you about severity of the disease and treatment is based on severity only. You may need inhaled bronchodilator (formoterol or salmeterol) and inhaled corticosteroids (ICS) (budesonide or fluticasone). Don't worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
