OH YES! I never had any allergic symptoms until I was 23. Then all heck broke loose. Eyes were ichey and could no longer wear contacts. Eye Dr. said go to the allergist. Went there for testing and had big time reaction to dust and yeah it sounds gross "vacuum cleaner bag contents". That was 12 years ago. I presently take Singulair tab. and Nasonex. I did go last year for another "scratch" test with a new allergist. Results are still the same. I can't go more then a day or two without taking my medicine. Go to an allergist and satisfy your curiosity. Good luck.
