我是做搬运工的，大概搬东西也三四年了，这个腰，还有背大概是3年前开始有点疼。之前啊，稍微休息一会就没那么疼了。不过这三年呢，就是这个腰疼一直反反复复的，平常一疼，我吃点止疼片吧，再休息那么一会，也就好了。 大概上个月，这个腰又痛的不行，而且左侧大腿还疼，休息一阵子也没见好，就想着来医院看看帮吧。上周准备搬东西的时候，发现这个腰突然就弯不下去了，走路时候，左边这个后脚跟也疼的不行。
(I work as a mover and have been doing this for about three or four years. My lower back and upper back started hurting a little about three years ago. Before that, the pain would go away after resting for a short while. But over the past three years, the lower back pain has kept coming and going. Usually, when it hurts, I take some painkillers and rest for a bit, and it goes away. About a month ago, the lower back pain became unbearable, and my left thigh started hurting too. It didn’t get better even after resting for a while, so I decided to come to the hospital to get some help. Last week, when I was getting ready to move some things, I suddenly realized I couldn’t bend over at the waist, and when I walked, the heel of my left foot hurt terribly.)
