When I woke up yesterday one muscle in my neck was totally in spasm. I threatened it by saying: "If you don't stop this, I am going to rip you right out of my body!"
Alas, it did not stop, so I used a towel and a piece of rope to make a neck brace, which really helped me keep from stressing my neck further.

(who is also my sister) was luckily in town and was able to help me demonstrate how you can make your own neck brace too.
