Patients with lumbar disc herniation can have the herniated disc partially retracted through traction and physiotherapy of the lower limbs, as well as muscle exercises, but is the disc completely normal after it is retracted? The answer is no, this is because after the lumbar disc herniation, most patients have significant degeneration of the intervertebral disc, moisture reduction, the elasticity and toughness of the intervertebral disc are worse than normal, so if these patients do not pay attention to the usual work and lifestyle after the disc is back in, long-term long standing and sitting, it will easily lead to the lumbar disc herniation again. Therefore, patients should pay attention to the usual exercise and maintenance after the lumbar disc herniation, mainly to exercise the strength of the core muscles of the lumbar abdomen, and maintenance is to avoid prolonged standing, prolonged sitting and local warmth, lying on a hard bed, etc.
