肩胛提肌怎么了

Levator Scapulae

Levator scapulae

颈根 / 肩胛骨内上角极常见

这块肌肉是什么

从上 4 节颈椎的横突斜向下连到肩胛骨的内上角。负责上提肩胛骨（耸肩的一部分），并帮助颈部侧屈、后仰，肩胛骨固定时还把头转向同侧。

为什么会不舒服

长期无意识耸肩（压力、单肩背重包）；头前伸、长时间低头看手机；侧头夹着电话；睡姿不良（落枕）；桌椅/显示器高度不当。

常见不适表现

"落枕"最经典的痛点——颈根到肩胛骨内上角那个又酸又硬的死结；转头受限（尤其转向痛侧）；肩颈交界僵硬发紧；早上起床最重；有时牵扯到肩胛骨上角。

缓解方法

拉伸：先低头再转向对侧腋窝方向看，同侧手轻扣后脑加压，保持 15 秒；用网球顶住肩胛骨内上角滚压；避免耸肩和单肩负重；换低枕头；把显示器抬高到视线水平。

Levator scapulae

Base of the neck / upper inner corner of the shoulder blade · Very common

What this muscle is

Slants down from the transverse processes of the top 4 neck vertebrae to the upper inner corner of the scapula. It lifts the shoulder blade (part of a shrug), helps the neck side-bend and tip back, and, when the shoulder blade is fixed, turns the head to the same side.

Why it gets uncomfortable

Unconscious shrugging (stress, a heavy bag on one shoulder); a forward head and long periods looking down at a phone; clamping the phone with the head tipped sideways; a poor sleeping position (a crick in the neck); desk, chair, or screen at the wrong height.

How it usually feels

The classic spot for a "crick in the neck" — that sore, hard knot from the base of the neck to the upper inner corner of the scapula; turning the head is limited, especially toward the painful side; stiffness where the neck meets the shoulder; worst on waking; sometimes it tugs the upper corner of the scapula.

What helps

Stretch: look down first, then turn to look toward the opposite armpit, and let the same-side hand rest lightly on the back of the head for 15 seconds. Roll a tennis ball into the upper inner corner of the scapula. Avoid shrugging and carrying weight on one shoulder. Use a lower pillow. Raise the screen to eye level.
