I am 20years old and have lived in the same neighborhood my whole life. I never suffered from allergies or any other nonsense growing up, but when I turned 18 I experienced my first severe allergic reaction (hives throughout the body and swelling of the hands accompanied by "seasonal asthma"). Allergy testing (skin test) revealed that I am allergic to grass and tree pollen. You can imagine the blow this was to an aspiring environmental scientist. Anywho two years later and I am trying to make spring my favorite season once again. I want to try immunotherapy but I don't have the time to commit myself to the shots and am not sure I am comfortable with sublingual therapy. So I've decided to expose myself to the allergens (walking through the park for as long as I can take it) as a form of self-immunotherapy. Can I dimish my sensitivity to allergens this way? I'm dying to enjoy the outdoors, running, and gardening again!
