It will be worth the money spent to get your neck injury checked out. I know Christopher Reeves didn't hurt himself by doing karate, but he did have a neck injury falling from a horse. I'm sure you have seen how he spends his time. You could have an impingement on your spinal cord in some way and all it needs is another blow to cause major damage. This can bear out the adage of a stitch in time saves nine. Good luck and use your common sense.
