Hi Khyati,
Thanks for your writing to HCM
Look your symptoms sounds like asthma symptoms with a definite variability with cloudy weather. I dont know whether you have family history of asthma or not. You should continue the treatment prescribed by your physician as the drugs are given rightly and on the basis of asthma symptoms. I also advised you to consult a pulmonologist to get yourself locally examined and have a pulmonary function testing with bronchodialator reversibility. If you are proved to have asthma then you should be managed appropriately to control your asthma. You should avoid dust, cold environment, cockroaches, pollution, house dust mite, smoke etc because all of these are potential asthma triggers. You should not take those drugs if you are know allergic to them.
Thank you.

Hi,
Welcome to HCM
After going through history because there is seasonal association, Bronchial asthma is possible your treatment also suggest that possibility.
Another possibility is post viral acute bronchitis.
You can get PFT pulmonary function test when you are not takig drugs and a post bronchodialator improvement can be assesed. A detail allegy work may be done including serum IGE level and allergy testing then specific allergen can be de sensitized or avoided.
In general exposure to pollens,dust,fungus pet animal can be avoided.
Increase your immunity and lung capacity by taking yoga and pranayam and exercises.
One can avoid sudden changes in temperatures like AC rooms and going out side.
Take your inhalers as advised by doctor and take care of your diet also if overweight reduce it and avoid fermented foods and any specific food which increases your problem
Take care
Good luck to you.
