Kinked back?

You know how sometimes if you move suddenly in an odd way you can get a kink in your neck? WELL, I'm not really sure what happened, but somewhere in between the time I picked up my clean laundry from the drier and when I set it down in my room (after lugging it up 4 flights of stairs) I discovered that I seem to have kinked my entire upper back. Yes folks, I can no longer turn my chin past either shoulder and it not only hurts my neck, but every muscle in between my shoulder-blades. Sometimes I amaze myself with what I am capable of... Anyway, I slept on a cold pack and now I'm trying to get my mini hot pack to be situated such that it will cover a maximal amount of afflicted area. Any advice on how to over-come would be greatly appreciated.
