I've never been punched in the face, but I did have a basketball kicked rather hard into my face a few years back. My sensation was a bit different from the OP's though. I didn't feel any pain, but I didn't feel any numbness either. It felt like a small puff of air at most, and I didn't have any sensations of numbness or anything like that either, I just felt perfectly normal. At first I thought that it hadn't even hit me, but my nose an gums soon started bleeding, and my glasses were a little bent at the side.
It was a very strange occurrence for me, seeing as I'm usually not numb or indifferent to pain. Oh well, it happened with most of my class watching, so shrugging it off completely while they all gasped did at least earn me a few badass-points ;P
