Thirdly, whether the fourth lumbar herniation is serious depends on the clinical symptoms. If there is only lumbar pain without symptoms of lower limb numbness, pain or diaphoresis, it is not very serious and only requires usual maintenance and regular follow-up. It is important to avoid prolonged bending, bending work or sitting for a long time, or getting cold, so as to avoid further aggravation of lumbar disc herniation. If there is lumbar pain, accompanied by numbness and pain in the lower extremities, or if there is constipation or incontinence, it is more serious and often requires active treatment, such as traction of the lumbar spine, oral medication, and physical therapy of the waist, which can relieve the lumbar disc herniation, and most patients have effects after conservative treatment. Surgery may be required in rare cases.
