appears to be allergic in nature and the allergens may be from the slaughter house where large number of animals are present at a given time. Allergens may be from the animal proteins
or fungal spores as fungus grows in hot and humid and unhygienic conditions. Your cough may be a form of asthma
called `cough variant asthma`. You may find out the allergens by skin testing but it`s a tedious process and it will be difficult to say if allergens are originating from this particular place. For your cough take a mantair lc and aerocort inhaler If it does`nt help, consult a pulmonologist.
