The most common cause of sciatica is a herniated disc in lumbar 4 and 5, and lumbar 5 sacral 1 limiting the freedom of nerve root movement and producing chemical and/physical nerve root irritation/compression symptoms. Some patients can be treated conservatively to achieve a stable condition without the need for surgery in order to control the disease, especially in the elderly and in patients with more underlying disease. 1. First, the appropriate case is selected: lumbar disc herniation, spinal stenosis, diabetic neuritis, and drug-chemical neuritis with pain as the main complaint, indicating that the patient is currently suffering from aseptic inflammation of the nerve root as the main damage, and the therapy is preferred. 2, clear lesion segment, accurate injection treatment: before treatment must achieve the symptoms, signs and imaging of the three coincidences, and in the course of treatment according to the efficacy of continuous summary adjustment. 3, paravertebral injection choose intervertebral foramen outward approach. Patients mostly need several injections for treatment, and the outward approach does not directly puncture into the spinal canal, which can achieve the purpose of nerve root anti-inflammation, but also prevent the risk of nerve injury and avoid aggravating the adhesions in the spinal canal. 4, the injection of drugs to contain mixed spin glucocorticoids, local anesthetics and VitB12, not to use the mechanism is unclear, the efficacy of the drug is not sure. 5.Give the patient a detailed suggestion of daily life care. Control of sciatica is a long-term comprehensive treatment process, and the importance of daily rest and health care methods is crucial to consolidate the treatment effect and prevent recurrence. Do not hold the idea of “the best solution”. 6. Do something and do not do anything, avoid overstepping and over-medication. For patients with significant neurological metamorphosis in the short term, such as progressive numbness, it is recommended that patients adopt radical techniques at an early stage, so as not to delay the patient’s treatment and not to cost the patient extra time and consultation fees for conservative treatment before opening the surgery.
