I'm not sure what I did, but I have wrenched my neck. I've had a seriously stiff neck for about 4 days now. I wonder if maybe wrestling my dog did it to me. When she sees other dogs, she goes ballistic and I have to wrangle her and make her sit and settle down. She is 73 pounds, so not easy to handle. I don't know if that's the reason my neck hurts, but I can't think of anything else I did.
I was thinking about something a friend told me. He does alternative healing, and works with kinesiology. He believes that if you say things like "what a pain in the neck" that you then will get a pain in the neck. My Dad always says, "Oh my aching back" when something goes wrong. I wonder if his back hurts. I think that even though I don't really believe that saying something gives you the malady, it has still influenced me because I find myself having an aversion to saying, "What a pain in the butt". I can't think of any other sayings like that, but I do often say, "What a pain in the neck". I don't know, but I don't think that's why my neck hurts. :)
