头后小直肌怎么了
Rectus Capitis Posterior Minor
Rectus capitis posterior minor
这块肌肉是什么
从第1颈椎后弓连到枕骨，使头轻轻后仰。
为什么会不舒服
头稍微一动它都在工作；高枕头把第一颈椎和枕骨挤在一起。
常见不适表现
最靠近头骨的一小点发紧；躺下换枕头高度时能感觉到。
缓解方法
仰卧不用枕头垫太高，后脑放平，只做慢呼吸。不要按得很深。

Rectus capitis posterior minor
Under the occiput · Very common
What this muscle is
From the posterior arch of the first neck vertebra to the occiput. It tips the head gently back.
Why it gets uncomfortable
It works on even a small movement of the head; a high pillow packs the first neck vertebra against the occiput.
How it usually feels
A small tight spot as close to the skull as it gets; you can feel it when you lie down and change the pillow height.
What helps
Lie on your back without a pillow stacked too high. Let the back of the head lie flat, and only breathe slowly. Do not press deeply.
