Such as dust, pollens, ragweed, hay, palo verde trees, molds, etc.. I'm also allergic to cat
saliva and many foods.
I used to take allergy
shots, for most of my allergies because I live in one of Arizona's main farming communities. However, I went off them years ago and haven't had many problems since.
My doctor gave me an asthma test a month ago and it came out negative. She didn't see the need for any x-rays. Instead she put me on Singulair and R-Tanna as I had mentioned before.
