Debbie,
Sorry about the sore, stiff neck.

I used to get that a lot when I was younger.

It doesn't happen as much anymore. For me, I think I would sort of wrench it when turning around while driving to either back out, or break up an argument in the back seat when our boys went through that stage.
The salonpas sounds like a good idea. I hope you can get some and it will help. Call the doctors too and maybe they can suggest something as well. Feel better soon!
Sox,
Way to go on the weight loss and your blood pressure! That's awesome!
