谢谢你的留言。才看见。 我已经跑了十几年了。记得才跑时，有过不仅是腿僵硬，而且是疼，还绑过腿带子。 后来是一天跑长点，一天跑短点。每次一开始是慢跑个一到两个英里，再加速。慢慢的腿不疼了。我现在也是要跑一到两个英里再加速。 跑步的姿势也很重要。另外，少在水泥地上跑。 希望这些能帮到你。

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.
