Ugh, I feel for you, but I did the opposite....I outgrew all my pollen allergies. I had never had any symptoms whatsoever while we lived in NJ. Moved to KY in January of '74 (I was 10) and that summer I went out to ride my bike in a field close to the house. I had a reaction so strong to something there that I couldn't make it out of the field before my eyes swelled shut. Someone had to get my mom who had to walk me home. Back then the therapy was steroid injections (go figure...) which worked for me. I hit about 18 or 19 and the symptoms just simply stopped dead. Nothing. Same field just down the street with all the same crap growing in it. It was the weirdest thing. To this day (I'm 45 now) I've not had another seasonal allergy symptom. Oddly, my son has pretty bad seasonal allergy symptoms, he tested sensitive to tree pollen mostly.

Good luck...its a sucky existence, I know.
