Snot vs. Anesthesia

I am trying to fly without steroids today. Of course, today is also much worse on the boogie front. Possibly looking at a sinus infection, although it's too soon to say for sure.

So...what level of sick is too sick for anesthesia?

I know I need to call and ask, but I'm hoping if I wave my daughter's little made-in-China fairy wand around and consult the magic 8 ball (aka the internet) that things will magically work out.
