肱三头肌内侧头怎么了
Medial Head of Triceps Brachii
Medial head of triceps
这块肌肉是什么
贴在肱骨后面，被长头和外侧头盖住，连到尺骨鹰嘴，伸肘。
为什么会不舒服
细小的伸肘也一直用它；另外两头放松了深面还紧。
常见不适表现
上臂后侧深层闷酸；完全伸直肘的最后一点发紧。
缓解方法
举手屈肘，手去摸对侧肩胛，另一只手在肘后轻轻帮忙，停20秒。只沿上臂后侧慢推，不要戳肘后内侧的麻点。

Deep back of the upper arm · Common, after training
What this muscle is
Lies on the back of the humerus, covered by the long and lateral heads, and reaches the olecranon of the ulna. It straightens the elbow.
Why it gets uncomfortable
Even small elbow-straightening keeps using it; the other two heads have eased and the deep one is still tight.
How it usually feels
A dull deep ache on the back of the upper arm; tightness in the very last bit of straightening the elbow.
What helps
Raise the arm, bend the elbow, and reach toward the opposite shoulder blade. The other hand helps gently behind the elbow. Hold 20 seconds. Push slowly only along the back of the upper arm. Do not poke the numb spot on the inner back of the elbow.
