Lumbar disc herniation is the main cause of lumbar pain. It is a common disease in which the lumbar intervertebral disc ruptures and the nucleus pulposus tissue protrudes, stimulating or compressing the corresponding nerve roots and producing symptoms of lumbar pain. Most patients with lumbar disc herniation often have low back pain at the beginning, accompanied by a series of clinical symptoms such as numbness and pain in one leg or foot at the same time or after the onset of low back pain. Typically, the pain is radiating from the lumbar region to the hip, the back of the thigh, the outer calf, and the foot, and is aggravated by bending over, sneezing, coughing, and straining to defecate. In a small number of patients, leg pain and numbness occur first, followed by lumbar spine pain symptoms. The vast majority of patients with lumbar herniation can be improved by conservative treatment. Only 1 to 5 percent of patients with lumbar disc herniation must be treated surgically. There are many conservative treatments for lumbar disc herniation, including the following treatments: 1. bed rest, sleeping on a hard bed Especially during acute attacks, the purpose is to relax the symptoms of lumbar muscle spasm and reduce the pressure on the lumbar disc. After the pain is relieved, you can wear a medical lumbar circumference for proper activities to relieve the lumbar muscle spasm and restore the balance of the human lumbar muscles. 2.Physiotherapy Mainly local heat, low and medium frequency electrical stimulation therapy, infrared therapy, magnetic therapy, etc., the latest application of Chinese medicine directed drug permeation therapy is more effective. Its role is to eliminate local muscle inflammation, relieve muscle spasm, so as to achieve analgesia and reduce the role of interdisc pressure. 3.Tui-na, massage and acupuncture are generally suitable for acute pain period, otherwise it is possible to aggravate the symptoms after massage and tui-na in serious cases. 4, traction generally need to be carried out in the hospital, more suitable for patients with bulging type, some patients do not adapt and can not adhere to this therapy. 5 drug therapy If the patient has heavy pain, you can take non-steroidal anti-inflammatory pain medication, (contraindicated in patients with gastroduodenal ulcer); at the same time take neurotrophic drugs; oral Chinese medicine to activate blood circulation and remove blood stasis may also play a role. In more severe cases, intravenous infusion of anti-edema and nerve-nourishing drugs is required. Nerve block therapy Nerve block is the use of puncture method to directly inject drugs around or near the nerve to block the nerve signal transmission of pain. Its characteristics: 1. reliable analgesic effect. 2. important for diagnosis of disease. 3. selective treatment range. 4. rapid therapeutic effect. 5. small adverse effects. Its mechanism of action: blocking the nerve conduction pathway of pain, blocking the vicious cycle of pain, improving blood circulation and eliminating inflammation. The nerve block treatment of lumbar disc herniation can generally be taken in the outpatient clinic sacral block therapy can achieve better results, which is also the most used and effective therapy in the pain clinic. For more severe and recalcitrant patients, imaging-guided nerve root block at the lesion is also feasible, which is safe, effective and minimally invasive, and has been successful in many cases.
