Rectus capitis posterior major

Under the occiput · Very common

What this muscle is

From the spinous process of the second neck vertebra to the occiput. It tips the head back and turns it to the same side.

Why it gets uncomfortable

Looking down for a long time, so this small muscle on the second neck vertebra stays contracted; a forward head.

How it usually feels

An ache directly under the occiput; stiffness when you look up into the distance; the head feels heavy.

What helps

Tuck the chin gently, look straight ahead, and rest the back of the head against something a little high. Hold 20 seconds. If a headache suddenly gets much worse, see a doctor.
