###Human: Will travelling to a place with high rates of pollution affect my lungs? ###Assistant: Hello. In case all your investigations are normal then you probably have acute bronchitis or associated anxiety. In your case scenario, my suggestion would be antiallergic like Levocetirizine and Montelukast once daily. Addition of Etizolam as an antianxiety drug would help you further. Consult your specialist doctor, discuss with him or her and start taking the medicines with their consent. I hope it helps you. For more information consult a pulmonologist online -->
