Every morning before breakfast I stretch and exercise for about 45 minutes. Afterwards I take a shower, eat breakfast, and then I hit balls for a little while before work. When I was stretching this morning, I was laying on my back on the floor just stretching my arms, neck and back, and I felt something in my neck kind of pull. I stopped stretching and my neck hurts so bad when I turn it to the left even slightly. I can't even get halfway down in my stance without it hurting very badly. I am a young guy who is very physically fit, this has never happened before. Does anyone know if playing pool for so many years could have weakened a spot in my neck, and that's why I pulled something when I was stretching? Either way I am pretty worried and upset that I won't be able to play pool for a long time, it's pretty bad. I'll be going to see a chiropractor on Friday so hopefully this can be fixed, but the way it feels, it feels pretty stuck. Has anyone had anything like this happen to them?
