Bad Sign: You have been given a local anesthetic, and during the proceedings the doctor keeps asking you “Does this hurt?” in a tone that suggests he is surprised that you are saying no.
Interpretation: When that anesthetic wears off, it is going to hurt like a mother.
I have been trying to avoid commenting on the "hurts like a mother" but have failed.

I apologize. I did think twice about using it, but failed.
