A herniated lumbar disc can be cured. The reason why there is the saying that a herniated lumbar disc is incurable for a long time is that most conservative treatment is used. Conservative treatment can make the disc retract as much as possible and no longer compress the dural sac and nerve roots of the spinal cord though. However, because there is no way to ensure 100% standard of daily sitting posture or to not bend and bear weight in daily life, people usually relapse in the near future, and once they do, they are considered incurable. Patients who have had surgery to remove a herniated lumbar disc are also at risk of recurrence because the disc is not completely removed.
