After going my entire life, well all 25 years of it anyways, I finally went to an allergy specialist. She did a skin graph and informed me that I was allergic to every type of tree, grass, mold, and most citrus and fruits, along with dogs, cats, etc....it just keeps going. The one thing I wasnt allergic to was.....you guessed it...a horse!
She perscribed me Xyzal that you take once daily. I too would sneeze like crazy around any type of hay, or grass, but since I've been taking this, it doesnt effect me at all!
She also gave me some sort of nazal spray and I've been using it daily as perscribed.
It done wonders for me. Hope this helps!
