Dural sac and nerve root compression, may be caused by lumbar disc herniation or ligamentum flavum hypertrophy, calcification, lumbar vertebral osteophytes, etc., generally can not be self-healing, and need to be under the guidance of a doctor to receive regular treatment. If the lumbar disc is herniated, there is no way for the disc to return, retract or disappear without regular treatment. If the pressure on the dural sac and nerve root is caused by a bone spur, it cannot heal itself without cutting out the bone spur completely. If the dural sac and nerve root compression is caused by hypertrophy and calcification of the ligamentum flavum, it cannot be cured without cutting off the hypertrophied and calcified ligamentum flavum. If symptoms such as numbness and weakness of limbs occur, it is recommended to go to the hospital in time to get a clear diagnosis.
