尊敬的编辑同志: 您好! 我是一名高三年级的男生,从小就是扁平足,从前还不太显著,从去年到现在,我每天都坚持长跑,结果脚却越来越糟糕。平时总感到又累叉疼,一剧烈活动,脚底下的骨、肉疼痛难忍,一活动脚,踝关节就发出清脆的“叭叭声”。甚至每天的正常走路运动都受影响,现在我不得不减少运动和锻炼,停止长跑 Dear Editor: Hi, I am a third year boy. I was a flat foot from an early age. It was not obvious before. From last year till now, I insisted on long distance running and my feet were getting worse and worse. Usually feel tired and tired, a violent activity, under the foot of the bones, meat pain unbearable, a moving foot, the ankle issued a crisp “horn.” Even the normal daily walking activities are affected, and now I have to reduce the exercise and exercise, stop the long-distance running
