I don't understand how some MDs can not realize it. It is well documented that candida trigger the immune response to a chronic Th2 side. Th2 response is against allergens, parasites, extracellular pathogens, toxins, etc. Your immune system is overactive in a Th2 response, so, normal things like dust, perfum, chemicals, will cause you a reaction. When candida and other causative factors be eliminated, the Th1 and Th2 functions get balanced again, and those triggers will be tolerated without any problem. I thing it is time for some MDs to do their homework.
