Soror 2D did the honors for the allergy quiz... here is one for sinuses.

I took the quiz, and I think that I have been having these infections since college, but I thought they were migraines. Up until recently, Eccedrin Migraine would do the trick. Now nothing works, and I'm miserable.
You know, how do you know if you have something or not, if you don't even know it exists??

I'm a little perturbed by the fact that the doctor didn't even mention this. It's like you have to go into the office with a self diagnosis. WTF? They get paid all that money to guess. Now I know why it's called a 'practice.'
