I was outside waiting for the school bus to drop off the kids....cold , I was holding my neck down to keep my chin warm in my zipped coat....when I raised my neck up, I got a cramp in my throat and back of my tounge....I have never felt that before and got nervous. I was afraid it was going disruptt my breathing. I m fine, but wonder why it happened...I assume it was because I was holding my head down hard and tightened those muscles and when realeasing them, muscles cramped
