and dust, histamine

and mucus production.
Please contact an allergic specialist and get skin tests like skin ***** test done. In this a small amount of allergen is introduced into the skin of the forearm and the reaction of the skin is noted. If there is any redness then that person is allergic to the allergen introduced.
