Well, the good news is that out of 47 different allergens, I'm not allergic to any of them!
The bad news is, I'm not allergic to any of them. :-/ So now what? Why do my lungs get so angry at night, and when it's cold out?
For now, they are going to treat me as though it's asthma, because that's the most likely explanation. *sigh* I wish I'd come away with a better answer, or at least a more definitive diagnosis. I still don't understand why it's so intermittent.
At least I'm not allergic to any animals...
