Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, we should definitely rule out bronchitis in your case because bronchitis is common in patients with asthma in the past. So consult pulmonologist and get done clinical examination of respiratory system and 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. If PFT is showing obstructive defect then you may need inhaled bronchodilators (formoterol or albuterol) and inhaled corticosteroid (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.
