What nerves does C4 C5 control?
The C4 dermatome covers parts of the neck, shoulders, and upper part of arms. C5 helps control the deltoids (which form the rounded contours of the shoulders) and the biceps (which allow bending of the elbow and rotation of the forearm). The C5 dermatome covers the outer part of the upper arm down to about the elbow.

What are the symptoms of a pinched nerve at C5 C6?
C5-C6 (C6 nerve root): Pain, tingling, and/or numbness may be felt in the thumb side of the hand. Weakness may also be experienced in the biceps (muscles in the front of the upper arms) and wrist extensor muscles in the forearms. The C5-C6 disc is one of the most common to herniate.
