The C4 nerve is associated with the C3-C4 disc. Tingling in the back
of the neck is a common symptom. |

 |
The C3-C4 level is in the middle part of the
neck as shown.

When the neck joint (facet) connected to
this level gets irritated, it refers pain to the top of the neck,
middle of the neck, and into the middle part of the upper back,
just below the shoulder blade.
