See your doctor.: You have multiple exacerbations of your asthma. Upper respiratory infections produce increased mucus which further narrows your airways. Your occupational exposure to dust provides chronic airway irritation. You need to discuss these factors with your physician, to reduce your acute inflammation and make a plan to reduce chronic irritation.
