Inner back of the thigh · Common
What this muscle is
From the sit bone to the inner tibia. The tendon is thin and long. It bends the knee and extends the hip.
Why it gets uncomfortable
A sudden acceleration, or kicking with the top of the foot; after long sitting this long tendon shortens; you cannot reach your feet when you bend.
How it usually feels
The thin tendon on the inner back of the thigh feels tight; bending the knee against resistance pulls behind the inner knee; the lower edge of the sit bone aches when you sit.
What helps
Lie on your back, straighten this leg, pull the toes up, and draw the leg gently toward you with a towel. Hold 20 seconds. Do not bounce.
