What this muscle is

From the breastbone and collarbone to the mastoid on the skull. The most visible muscle in the neck. One side turns the head to the opposite side; both sides bend the neck forward. It also helps with breathing.

Why it gets uncomfortable

A forward head from a phone or computer; looking at a screen off to one side for a long time; a pillow at the wrong height; anxious, shallow, fast breathing.

How it usually feels

A sore ache on one or both sides of the neck; a neck-related headache at the temple, behind the eye, or on the forehead; ringing in the ear; a deep pain behind the eye; a sense of dizziness.

What helps

Rotation stretch: turn the head to one side, then press lightly. Raise the screen to eye level. Ease the forward head. Get the eyes checked.
