Regards from DoctorSpring
Are you allergic, asthmatic in childhood or having any similar history in family?
Hope your past medical history is asymptomatic.
Presuming a negative answer to asthmatic background and past medical history, I strongly feel that you might be suffering from Hypersensitivity Pneumonitis (HP). The differential diagnosis will be Reactive airway dysfunction syndrome(RADS). However HP seems more fitting.
How do you feeel your symptoms are associated to duty days? Are the symptoms aggravated specifically on work?
I would suggest that you get an X ray of the chest, Pulmonary function test and a High resolution CT scan of chest.
I am inclined to think you have a sub acute HP and may benefit from a short course of steroids, and change in the work environment. However I suggest consulting a pulmonologist before taking a decision to change your work.
Do get the above tests done and update me. Feel free to follow up.
