Leg pain is a symptom of lumbar disc herniation, and when there is a more severe leg pain, the first recommendation is to rest. Secondly, go to the hospital in time for examination to clarify whether the next step of diagnosis and treatment is needed. Lumbar disc herniation leg pain is due to lumbar disc herniation compressing the nerve root. The first thing to do is to determine the degree of compression. Therefore, you need to go to the hospital to do lumbar spine MRI, through the lumbar spine MRI to determine the lumbar spine disc herniation site, the degree of herniation, the nerve compression, whether there is no degeneration, ischemia and other conditions. If the patient only manifests leg pain and the lumbar MRI shows that the nerve is only slightly compressed, conservative treatment can be used to alleviate the clinical symptoms in the first place. ① bed rest, generally strict bed rest for three weeks, with waist cuffs gradually down to the ground activities; ② oral non-steroidal anti-inflammatory analgesics ③ traction method, pelvic traction is most commonly used; ④ Chinese medicine therapy, including traditional Chinese medicine fumigation, tui na, acupuncture, and oral activation of blood circulation and elimination of blood stasis of the Chinese medicine preparations, and so on. If the patient not only has the manifestation of leg pain and numbness, but at the same time the MRI of lumbar spine suggests that the nerve root or dural sac is severely compressed and twisted and deformed, surgical treatment should be considered. Traditional open surgery, microsurgical lumbar disc removal surgery and minimally invasive disc removal surgery are used according to the patient’s specific situation. For patients who do not respond to conservative treatments and do not meet the criteria for surgery, a nerve block is an excellent option. Nerve block is a therapy in which analgesic and anti-inflammatory drugs are injected directly into the vicinity of the diseased nerve root. Therefore, for patients with leg pain caused by lumbar disc herniation, it is important to first make a clear diagnosis, grasp the condition, and then adopt a reasonable treatment method.
