From your description it is apparent that you are suffering asthma
. If possible avoid the allergens that you have mentioned. Normally inhalers are the answer to asthma but in your case they seem to make it worse. Probably the propellant in it is causing asthma like symptoms. You have not mentioned the inhalers that you are taking. You change your brand or take oral steroids
or methyl prednisolone as short course when symptoms develop. You should repeat ct scan
and PFT after 6 to 12 months to rule out any occupational lung disease
which takes time to menifest.
