我一直在国外工作，去年10月份发现腰疼同时伴随左腿坐骨神经疼，就去当地医院检查，医生让做MRI，检查出来后也没有说什么（说了也听不太明白，我的英语水平只够对付生活和工作，医学方面的搞不懂），开了些药和维B6注射，治疗一段时间到现在也没有好转。我把检查结果贴上来，麻烦您给看看到底是什么问题，谢谢！
-Partial straightening of the lumbar curve with good vertebral alignment.
-Normal bone marrow signal pattern of the lumbar vertebrae with no evidence of marrow depletion or infiltration.
-Reduced height and bright T2 signal of the lumbar disc L5-S1 denoting dehydration.
-Modic type II marrow fatty degeneration seen at the opposing vertebral and plates of L5-S1.
-L3-L4 mild disc bulge seen effacing the anterior epidural fat, indenting the theca with no evident neural compromise.
-L4-L5 mild disc bulge seen effacing the anterior epidural fat, indenting the theca with no evident neural compromise.
-L5-S1 annular tear with diffuse disc bulge, posterior central, left para central & pre foraminal broad based disc protrusion seen effacing the anterior epidural fat, indenting the theca, mildly encroaching on the right neural foramen with pre foraminal and foraminal encroachment on the left nerve root pathway.
-Normal position and signal pattern of the conus.
-Normal dimensions of the lumbar spinal canal with no evidence of spinal canal stenosis.
-Moderate arthritic changes of the apophyseal joints noted at L5-S1 posteriorly compromising the lateral recesses.
-No pathological para vertebral soft tissue masses.
