Perhaps we all have such an experience, after a long time bending over, working at a desk, staying up late on the Internet or driving and straining, suddenly appearing back pain, many people do not take it seriously, endure it and pass, without formal diagnosis and treatment. Gradually, as people get older, they develop chronic low back pain to a greater or lesser extent. In daily life and in emergency clinics, we often encounter the question: what to do about low back pain? 1, first of all, it is still necessary to prevent, avoid prolonged bending, prolonged ambulatory work, prolonged late night surfing or prolonged driving. To participate in outdoor activities and physical exercise regularly. It is very scientific for students to attend classes for only 45 minutes, which is to let students rest their whole body. 2, if there is acute low back pain, the first thing is to rest in bed. In the clinic, many people do not pay attention to bed rest and feel that only medication and infusion is the real treatment, which requires a change of concept. At the same time, oral anti-inflammatory and pain medications (such as Disulfiram, Fenbendazole, and Difenacoum) as well as Celebrex are taken to promote inflammation, relieve muscle spasm, and improve pain. Some patients are afraid of taking pain medication, they always think that “pain medication” is a kind of fearful drug, just like “drugs”, but this is actually a misunderstanding. At present, the commonly used anti-inflammatory and pain relief drugs are mainly NSAIDs and COX2 drugs, and the main side effect of NSAIDs is peptic ulcer. Both types of drugs are not addictive. Bed rest + pain medication is the best way to deal with early acute pain. 3.If the pain does not improve after the above 2-3 days of treatment or there is numbness in the lower limbs and radiating pain in the lower limbs, then you should go to the orthopedic department of the hospital, so what kind of examination should be done? The two tests are frontal and lateral x-ray of the lumbar spine and MRI of the lumbar spine. x-ray can understand the bony structure of the lumbar spine, while MRI of the lumbar spine can observe the segment and degree of disc protrusion, and also understand whether there are tumors in the spinal canal and whether there are metastatic tumors or infections in the vertebral body. In fact, this is a misconception. In clinical work, there are too many cases of missed diagnosis caused by a simple CT, especially missed tumors, and there are lessons in blood. 4, if the lumbar spine MRI is done after the disc herniation is not serious, then you can conservative treatment. Under the premise of bed rest and taking anti-inflammatory and pain-relieving drugs, hormonal anti-inflammatory and mannitol dehydration treatment can be given, and light weight intermittent traction (10-12kg in general) can also be given. If the protrusion is severe, then surgery should be considered. If it is a tumor, then whether it is surgery or chemotherapy or radiotherapy should be determined according to the results of the nature of the tumor. 5. In clinical practice, we often encounter such a treatment method – “small needle knife”. I only represent my own opinion, I do not recommend to do “small needle knife”, there is no meaning, but is damage to the back muscle.
