Oh, ugh. My friend's elder son is terribly allergic to ragweed, so, right about August 15th, he becomes completely house-bound until the stuff goes away again. I hope you can get some satisfactory treatment soon. Btw, have you tried a Neti pot? Thoroughly rinsing the allergens out of your nasal passages a couple of times a day might help, too. And it's cheap.
