安徽读者高先生:我在走路时出现下肢不适感半年多了,最近走路时间长会出现酸胀的感觉,休息一会又可以继续行走。我还发现走路的时候身体向前倾一些能多走一段距离。请问这是怎么回事?你下肢出现的这种症状有可能是椎管狭窄。而走路时身体前倾,其实是为了减轻疼痛的一种代偿性姿势。身体前倾,可以避免黄韧带折叠等可使腰椎椎管狭窄加重的因素, Mr. Gao, Anhui Reader: When I was walking, I experienced discomfort in the lower extremities for more than six months. I recently felt soreness when I walked for a long time and then continued for a while. I also found myself walking a bit further when I was walking. May I ask what is going on? The symptoms of your lower extremity may be spinal stenosis. And walking forward when the body is actually a compensatory posture to relieve pain. Leaning forward, you can avoid such factors as the collapse of the ligamentum flavum can increase the stenosis of the lumbar spinal canal,
