I just recently found out that I have really bad allergies to dust and grass. I always thought the constant headaches and all of the other symptoms were something else. Allegra, Claritin, Beconase and Flonase don't work for my post nasal drip and headaches. Does anyone else feel like their throat is swollen and have little bumps on the back of it? Is this due to allergies? I also have an anxiety problem and wonder if it is due to that? What medications have worked best? Thanks for the help.
