The onset period of lumbar disc herniation must be strictly bed rest, do not go down in the activity or even exercise, which are very dangerous. This is because the onset of lumbar disc indicates that the nerve roots are significantly compressed and the corresponding inflammatory reaction occurs, leading to edema of the nerve roots, which then often causes the inflammation or swelling of the nerve roots to pull, and the compression will be more serious, thus causing irreversible damage to the nerve roots or cauda equina, which will lead to serious sequelae. So the onset of lumbar disc herniation must be strictly bed rest and related treatment to reduce the inflammation of the nerve root or cauda equina, so as to restore the corresponding function, if exercise is very dangerous, it is strictly forbidden to move down to exercise.
