I've had asthma most of my life (controlled w/steroid inhaler and antihistamines) Mostly problems result from allergens, but recently I've had problems from irritants, such as plaster dust and cement dust. I've gotten wheezing sounds deep in the lungs (heard by doc), lung spasm, and labored breathing. It takes numerous weeks to recover from this. Oddly, my peak flows stay in the normal range even though my lungs are obviously not functioning well.
I'm hoping to get some information about this irritant-induced asthma, esp as it seems different from the allergy-induced.
