I get sick every spring, always at least once, usually twice. I end up getting bronchitis and needing antibiotics after the allergies lead to an actual infection. I don't want to have to use antibiotics all the time but I end up getting so sick and my chest burns, and that's the only thing that makes it stop.
I also have allergic reactions to cats and dust. The first makes me sad because I love kitties. Neither of those are as bad as the tree pollen which makes me sick in Spring though.
