[|Human|] Hello Doctor, my aunt who is 58 years old is suffering from severe, continous cough for the last 3 months. Reported negative for TB and lung infection tests. Antibiotics are giving temporary relief, but the unbearabe cough persists. What could be the cause and the best treatment for this?
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, we should definitely rule bronchitis in your case. Bronchitis means inflammation of airways. It can cause bronchospasm and this causes cough, expectoration, breathing difficulty etc. 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. You will 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.
