completely different kind of pain. Childbirth pain is different from injury pain, and injury pain is different than dental pain. IMO, dental pain is the worst of the three.
That, and you have nothing to show for the pain afterward, no sense of accomplishment and superhumanness like you experience after childbirth. I felt like a truck had just driven through my lower body, but other than that, I never felt better in my life than I did after giving birth.
After root canal, I merely felt sore and violated. --Jneen
