What causes extreme jaw bone ache and pain whenever I spend a lot of time on a cordless phone?

It could be the way you are resting the phone against your ear and shoulder. You may be causing undo stress to your jawt and shoulders.. Or you are holding your mouth in a different way when you talk. Try using an ear piece or playing around with the way you hold the phone.Do some stretches and neck and jaw exercises when you hang up.

Probably all the talking. Because I have to make this answer longer, I vote again for talking.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
