It must be from the needles themselves. My face was frozen for 6 hours! 6!!!
Stupid needles! I hate getting needles! I was a good girl though, I stayed very still until he was done, except that it didn't freeze me enough so he gave me two MORE needles!! I had no choice, so I lay there and was good until he was done, again.
Sigh, at least it's over. :) I like the dentist so much more when he's not around. ;)
