Allergies, ugh

Okay, I've accepted the fact that after 30-some years with no trouble, I've developed pollen allergies. I don't like it, but I've accepted it. I've even, grudgingly, accepted the fact that in my case it includes a pounding headache.

But *why is it only the right side of my face*? I'm getting very, very tired of blowing my right nostril.

I should think positively. My nose isn't half full, it's half empty.
