Hi, Thanks for writing your query. After reading your post, I would like to advise that you should try to avoid trigger factors like dust, smoke, cold, etc. You may need medicine whenever you are exposed to the triggers. Taking antihistamine like Fexofenadine 120 mg along with Montelukast will help in controlling your symptoms. I would also suggest that you should get yourself clinically examined and investigated. I hope this is helpful to you. Thanks.
