謝謝你的留言。才看見。 我已經跑了十幾年了。記得才跑時，有過不僅是腿僵硬，而且是疼，還綁過腿帶子。 後來是一天跑長點，一天跑短點。每次一開始是慢跑個一到兩個英裏，再加速。慢慢的腿不疼了。我現在也是要跑一到兩個英裏再加速。 跑步的姿勢也很重要。另外，少在水泥地上跑。 希望這些能幫到你。

go to UCSF to see specialist. My sister's son had the same kind of symptom when he was little. Doctor gave some kind of oil to apply to the hair, wait for two hours then wash it. About one weeks, the symptom will get better, and within two weeks, it completed gone.
