I'm scheduled to have an ACDF at C5/6 on April 9th and am wondering about something.
For YEARS I've been able to crack my neck and will feel a shock/zing down my left arm and it goes numb for a bit. Some of the time it feels like someone just knocked me out. I know the disc at C5/6 is touching the spinal cord and nerve canal.
My question is this - What exactly is going on when I crack my neck and I feel the shock sensation. The OS I'm using for the fusion has said when I crack my neck it's just the ligaments moving over the bones. I forgot to ask what causes the zinging sensations so I figured I'd see if anyone here would knows.
