It's uncomfortable and I have no idea what causes it.
I don't think it's nerves, I'm not in front of an audience.
Normally I sing below middle C, but I do occasion go higher. Ill try only singing low and see what happens.

Do you sing the F# above middle C often? It is a little known fact that F# (740Hz) is the resonant frequency of most teeth, and after a while will cause them to vibrate.
(P.S. Happy April Fools Day! Also, I have no idea, except that if your neck becomes sore as well, you may be tightening your throat and/or jaw muscles too much as you sing.)
